+@cindex SGML Declaration
+
+PSGML is a major mode for editing SGML documents, and includes a number
+of features for working specifically with HTML.  It works with GNU Emacs
+19.19 and later or with Lucid Emacs 19.9 and later.  PSGML contains a
+simple SGML parser and can work with any DTD.  Functions provided
+includes menus and commands for inserting tags with only the
+contextually valid tags, identification of structural errors, editing of
+attribute values in a separate window with information about types and
+defaults, and structure based editing.
+
+SGML, a language for encoding the structure of a document, is an ISO
+standard: ISO 8879:1986 ``Information processing -- Text and office
+systems -- Standard Generalized Markup Language (SGML)''.
+
+A good introduction to SGML is @cite{A Gentle Introduction to SGML}
+produced by Text Encoding Initiative (this is really chapter 2 of TEI
+P3). This can be found on
+@file{ftp://ftp.ifi.uio.no/pub/SGML/TEI/P3SG.DOC}.
+
+A SGML document has three major parts, in order:
+
+@enumerate
+@item
+SGML Declaration (@samp{<!SGML "ISO 8879:1986" @dots{} >})
+@item
+Document Type Declaration (@samp{<!DOCTYPE @var{name} @dots{} >})
+@item
+Document Element (@samp{<@var{name}> @dots{} </@var{name}>})
+@end enumerate
+
+The SGML declaration contains general information about character sets,
+concrete syntax, and SGML features used. PSGML does not use the SGML
+Declaration, it can be left out, and if included is ignored. Many SGML
+systems allow the SGML declaration to be defaulted.  PSGML always use
+the Concrete Reference Syntax but without limitations on
+lengths. Features used has to be indicated with variables (@pxref{SGML
+declaration}).
+
+The document type declaration specifies the valid elements and entities
+and how they can be nested. A document type is usually needed, but can
+reside in another file (@pxref{Managing the DTD}).
+
+The system declaration for PSGML:
+@format
+SYSTEM "ISO 8879:1986"
+   CHARSET
+     BASESET  "ISO 646-1983//CHARSET
+               International Reference Version (IRV)//ESC 2/5 4/0"

+@chapter Installing PSGML
+
+Place the @file{*.el} and the @file{*.elc} files in a directory where
+Emacs can find it (i.e. one of the directories in the @code{load-path}
+variable, you can add a directory to this variable in your
+@file{.emacs}.)  If you obtained PSGML without @file{*.elc} files, you
+can create them by letting Emacs byte compile the @file{*.el} files (use
+@kbd{M-x byte-compile-file}).  Parsing SGML in Emacs Lisp is slow and
+needs all the speed it can get.
+
+Put the following line in your .emacs:
+
+@lisp
+(autoload 'sgml-mode "psgml" "Major mode to edit SGML files." t )
+@end lisp
+
+You may also want to set up search paths for external entities,
+@xref{Entity manager}.
+
+The @file{psgml.info} is the documentation for PSGML in the info format.
+You can read this with the Emacs command @kbd{C-u C-h i}.  You can also
+install the file in your systems info directory and edit the
+@file{dir} file to include @file{psgml.info} in the menu.
+
+The info file @file{psgml.info} is created from the texinfo file
+@file{psgml.texi}.  The texinfo file can also be used to create a hard
+copy of the documentation.  To do this you need the @TeX{} program and a
+copy of @file{texinfo.tex}.

+@chapter How to invoke PSGML
+@cindex invoke

+@cindex major mode
+
+@findex sgml-mode
+PSGML defines a major mode called @code{sgml-mode}.  Files with
+extensions @file{.sgml}, @file{.sgm} or @file{.dtd} will
+automatically be edited in SGML mode.  To edit some other file in
+sgml mode, type @kbd{M-x sgml-mode @key{RET}} after finding the
+file.
+
+If you can modify the file you can add a @dfn{Local Variables} list
+(@pxref{file variables, , Local Variables in Files, emacs, The Emacs
+Editor}) to the end of the file.  This can make Emacs
+automatically set sgml mode and user options when the file is loaded.
+The simplest Local Variables list would look like:
+
+@example
+<!--
+Local Variables:
+mode: sgml
+End:
+-->
+@end example
+
+You can also put a line at the top of the file to tell emacs to use sgml
+mode:
+
+@example
+<!-- -*- sgml -*- -->
+@end example
+
+But remember that you can't have a comment before the @emph{SGML
+declaration}.

+@chapter The Entity Manager
+@cindex public identifier
+@cindex system identifier
+@cindex external identifier
+
+SGML can refer to an external file (really entity) with an
+@emph{external identifier}, this is a @emph{public identifier} or a
+@emph{system identifier}.
+
+A typical public identifier looks like
+
+@example
+PUBLIC "ISO 8879:1986//ENTITIES Added Latin 1//EN"
+@end example
+
+@noindent
+where ``ISO 8879:1986'' is the owner, ``ENTITIES'' is the text class and
+``Added Latin 1'' is the text description (and ``EN'' is language).
+
+A system identifier looks like
+
+@example
+SYSTEM "htmlplus.dtd"
+@end example
+
+@noindent where ``htmlplus.dtd'' is a system-specific identifier. 
+
+To map external identifiers to file names, PSGML first searches entity
+catalog files and then search the list of file name templates in the
+variable @code{sgml-public-map}.
+
+*** Describe the catalog format
+
+The catalog format is according to SGML/Opens resoution on entity
+management. The catalog consists of a series of entries and comment. A
+comment is delimited by @samp{--} like in a markup declaration.
+The entry types recognized are described in the following table.
+
+@table @samp
+
+@item PUBLIC @var{pubid} @var{file}
+The @var{file} will be used for the entity text of an entity
+with the public identifier @var{pubid}.
+
+@item ENTITY @var{name} @var{file}
+The @var{file} will be used for the entity text of an entity
+with the name @var{name}. If the @var{name} starts with a @samp{%} the
+rest of the name will be matched against parameter entities.
+
+@item DOCTYPE @var{name} @var{file}
+The DOCTYPE keyword indicates that an entity manager should use the
+associated |storage object identifier| to locate the entity text
+(to be used as the external subset) for a doctype declaration whose
+document type name is specified by the |entity name spec|.
+
+@item SGMLDECL @var{file}
+The SGMLDECL keyword indicates that an entity manager should use
+the associated |storage object identifier| to locate the entity
+text to be used as the SGML declaration.
+
+@end table
+
+The @code{sgml-public-map} variable can contain a list of file name
+templates where @samp{%P} will be substituted with the whole public
+identifier, owner is substituted for @samp{%O}, public text class for
+@samp{%C}, and public text description for @samp{%D}.  The text class
+will be converted to lower case and the owner and description will be
+transliterated according to the variable
+@code{sgml-public-transliterations}.  The templates in the list is tried
+in order until an existing file is found.
+
+Given the public identifier above and the file name template 
+@samp{/usr/local/lib/sgml/%o/%c/%d}, the resulting file name is
+
+@example
+/usr/local/lib/sgml/ISO_8879:1986/entities/Added_Latin_1
+@end example
+
+Note: blanks are transliterated to @samp{_} (and also @samp{/} to
+@samp{%}) and the text class is down cased.
+
+
+
+@defopt sgml-catalog-files
+This is a list of catalog entry files.
+The files are in the format defined in the SGML Open Draft Technical
+Resolution on Entity Management.  The Emacs variable is initialized from
+the environment variable @code{SGML_CATALOG_FILES} or if this variable
+is undefined the default is
+
+@lisp
+("CATALOG" "/usr/local/lib/sgml/CATALOG")
+@end lisp
+@end defopt
+
+@defopt sgml-local-catalogs
+A list of SGML entity catalogs to be searched first when parsing the
+buffer.  This is used in addition to @code{sgml-catalog-files}, and
+@code{sgml-public-map}.  This variable is automatically local to the
+buffer.
+@end defopt
+
+@defopt sgml-public-map
+This should be a list of file name templates. This variable is
+initialized from the environment variable @code{SGML_PATH}. This is
+the same environment variable that @file{sgmls} uses.  If the
+environment variable is undefined the default is
+
+@lisp
+("%S" "/usr/local/lib/sgml/%o/%c/%d")
+@end lisp

+@chapter Running an external SGML parser
+
+@kindex C-c C-v
+@findex sgml-validate
+PSGML can not validate an SGML document (see below what it can and can't
+do).  If you have a validating SGML parser, like @file{sgmls}, you can
+run the parser on your file with the command @kbd{C-c C-v}
+(@code{sgml-validate}).
+
+Some variables control this function:
+
+@defopt sgml-validate-command
+The shell command to validate an SGML document.
+
+This is a @code{format} control string that by default should contain
+two `%s' conversion specifications: the first will be replaced by the
+value of @code{sgml-declaration} (or the empty string, if nil); the
+second will be replaced by the current buffer's file name (or the empty
+string, if nil).
+
+If @code{sgml-validate-files} is non-nil, the format string should
+contain one `%s' conversion specification for each element of its
+result.
+
+The default value is @code{sgml -s %s %s}.
+@end defopt
+
+@defopt sgml-validate-files
+If non-nil, a function of no arguments that returns a list of file
+names.  These file names will serve as the arguments to the
+@code{sgml-validate-command} format control string instead of the
+defaults.
+@end defopt
+
+@defopt sgml-declaration
+The name of the SGML declaration file.
+@end defopt
+
+@defopt sgml-offer-save
+If non-nil, @kbd{C-c C-v} (@code{sgml-validate}) will ask about saving
+modified buffers before running the validate command.  The default value
+is @code{t}.
+@end defopt
+
+
+@kindex C-c C-o
+@findex sgml-next-trouble-spot
+The built-in parser can find some markup errors.  The command @kbd{C-c
+C-o} (@code{sgml-next-trouble-spot}) is the best way to use the built-in
+parser for this.  To check the whole file go to the beginning of the
+buffer and use @kbd{C-c C-o}.
+
+Some of the markup errors not found are:
+
+@itemize @bullet
+@item
+Errors in the SGML declaration.
+@item
+Errors in attribute specifications.
+@item
+Markup errors in entity replacement text.
+@item
+Omitted start-tags for empty elements.

+@cindex SHORTTAG

+
+PSGML does not understand the SGML declaration, it accepts one in the
+file but it is ignored.  If you have the SGML declaration in another
+file you can make @file{sgmls} use it when you use the @kbd{C-c C-v}
+(@code{sgml-validate}) command (@pxref{Validate}).
+
+PSGML has some options in what features it uses and what markup it
+creates.  You have to set these options to make PSGML's behavior
+consistent with your SGML declaration and personal preferences.
+
+@defopt sgml-omittag
+Set this to @code{t} if the SGML declaration has @samp{OMITTAG YES} and
+to @code{nil} otherwise.
+@end defopt
+
+@defopt sgml-shorttag
+Set this to @code{t} if the SGML declaration has @samp{SHORTTAG YES} and
+to @code{nil} otherwise.
+@end defopt
+
+@defopt sgml-always-quote-attributes
+If non-nil, quote all attribute values inserted after finishing edit
+attributes.  If this variable is @code{nil} and @code{sgml-shorttag} is
+non-@code{nil}, attribute values that consists of only name characters
+will not be quoted.
+@end defopt
+
+@defopt sgml-minimize-attributes
+Determines minimization of attributes inserted by edit-attributes.  If
+non-nil, omit attribute name if the attribute value is from a token
+group.  If @code{max}, omit attributes with default value.  Minimization
+will only be done if they produce legal SGML (assuming

+@chapter Document Type Declaration
+@cindex DOCTYPE
+
+@findex sgml-parse-prolog
+PSGML needs to know about the DTD you are using for many of its commands.
+You can use PSGML without specifying a DTD, it will then accept any tags
+and assume a content model of @code{ANY} with no omissible tags.
+
+If you have a @samp{DOCTYPE} declaration in your file, PSGML will try to
+parse this.  Either the first time you do something that needs to parse
+the document or with the command @code{sgml-parse-prolog}.  Big DTDs
+take some time to parse.  
+
+@vindex sgml-system-path
+@vindex sgml-default-dtd-file
+@vindex sgml-parent-document
+You can have the @samp{DOCTYPE} declaration in another file either by
+setting @code{sgml-parent-document} to the other file or by creating a
+saved DTD and setting @code{sgml-default-dtd-file} to that file.  If
+@code{sgml-default-dtd-file} contains a relative file name, the
+directories in @code{sgml-system-path} will be searched for the file.
+
+
+@findex sgml-save-dtd
+@findex sgml-load-dtd
+If parsing the DTD takes too long time you can save the parsed DTD in a
+file using the command @kbd{M-x sgml-save-dtd}.  Next time PSGML can
+load that file instead of parsing the DTD.  For PSGML to find the saved
+DTD you must either save the DTD using the default name or do a @kbd{M-x
+sgml-save-options} after saving the DTD.  To directly use an already
+parsed and saved DTD, load the file containing the saved DTD with the
+command @kbd{M-x sgml-load-dtd}.
+
+When the DTD has been parsed or loaded the name of the document element
+will be displayed in the mode line inside brackets.  If there was an
+error parsing the DTD or there is no DTD, the mode line will display
+@samp{[ANY]}.
+
+@defopt sgml-default-dtd-file
+This is the default file name for saved DTD.  This is set by
+@code{sgml-mode} to the buffer file name less extension plus the
+extension @code{.ced}, if that file exists.  Can be changed in the Local
+variables section of the file.
+@end defopt
+
+@defopt sgml-parent-document
+This can be set to the name (a string) of a file containing the
+@samp{DOCTYPE} declaration to use, or a list @code{(@var{filename}
+@var{doctypename})}, where @var{filename} is the name of a file
+containing the @samp{DOCTYPE} declaration to use, with the modification
+that the document type name is @var{doctypename}.
+@end defopt
+
+If you change the doctype you must execute @code{sgml-parse-prolog},
+changes in the doctype are not automatically recognized.
+
+@defopt sgml-custom-dtd
+Menu entries to be added to the DTD menu.  The value should be a list of
+entries to be added to the DTD menu.
+
+Every entry should be a list. The first element of the entry is a string
+used as the menu entry.  The second element is a string containing a
+doctype declaration (this can be nil if no doctype).  The rest of the
+list should be a list of variables and values.  For backward
+compatibility a single string instead of a variable is assigned to
+@code{sgml-default-dtd-file}.  All variables are made buffer local and
+are also added to the buffers local variables list.
+
+When an entry is selected from the DTD menu, the doctype declaration will
+be inserted, the variables will be set to the values in the entry and a
+local variables list will be created in the buffer.
+
+Example:
+
+@example
+   (("HTML" nil
+     sgml-default-dtd-file "~/sgml/html.ced"
+     sgml-omittag nil sgml-shorttag nil)
+    ("HTML+" "<!doctype htmlplus system 'htmlplus.dtd'>"

+the command will operate on the element after point.
+
+The attribute name will be read with completion.  If the attribute has a

+
+@end table
+
+Menu bar:
+
+@table @samp
+@item Markup
+Selecting from this menu will insert markup.  The menu contains
+sub menus with tags and with entities, some other markup and a user
+defined section.
+
+Sub menus:
+
+@item Insert element
+Pops up a menu of valid elements and insert start and end-tags for
+the selected element.  Selections from the menu works like the @kbd{C-c
+C-e} command.
+
+@item Insert start-tag
+Pops up a menu of valid start-tags and insert the selected tag.  The
+menu has the same start-tags as the completion list for @kbd{C-c <}.
+
+@item Insert end-tag
+Pops up a menu of valid end-tags and insert the selected tag. 
+
+@item Tag region
+Pops up a menu of valid elements and tag the region with the
+selection.  Selections from the menu works like the @kbd{C-c C-r}
+command.
+
+@item Insert entity
+Menu of all general entities defined in the DTD.
+
+@item Insert attribute
+Pops up a menu with all the attributes of an element.  The element is
+either the one which start-tag is immediately before point or the
+element after point.  Selecting from this menu edits the attribute
+specification list for the element.
+
+The menu has a sub menu for every attribute which declared value is a
+token list.  The rest of the attributes are collected in one sub menu.
+For the token list attributes, selecting a value will insert that
+attribute-value pair.  Selecting some other attribute reads the
+attribute-value from the mini-buffer and inserts the attribute value
+pair.
+@end table

+@kindex S-@key{mouse-1}
+A menu is also available directly with a mouse button click in the
+buffer.  In GNU Emacs it is the first mouse button combined with shift
+(@kbd{S-@key{mouse-1}}).  In Lucid Emacs it is bound to the third mouse
+button.  The mouse button click will pop-up a menu of valid tags or a
+menu of attributes if the point is in a start-tag.  The attributes menu
+works as the ``Insert attribute'' menu from the menu-bar.  The tags list
+is the list of valid tags described above for command @kbd{C-c <}.
+Selection from the tags menu works like the @kbd{C-c <} command, with
+the following exception:
+
+You can tag a region, with start and end-tag.  There are two ways to
+indicate the region to mark:
+
+@enumerate
+@item
+Use the normal mouse commands to mark region.  
+
+For this to work you must either use @dfn{transient mark mode}
+(@pxref{Transient Mark, , Transient Mark Mode, emacs, The Emacs
+Editor}) or set the option @code{sgml-tag-region-if-active} to non-nil
+(don't set this unless you are sure that you want it).
+
+@item
+Alternatively make a secondary selection, this is done by holding down
+the meta key and using the mouse buttons.  
+@xref{Secondary selection, , , emacs, The Emacs Editor}.
+Some window managers intercept these events, which makes it hard use the
+secondary selection in Emacs.
+@end enumerate
+
+@defopt sgml-balanced-tag-edit
+If non-nil, inserting a start-tag will also insert the corresponding
+end-tag.
+@end defopt
+
+@defopt sgml-auto-insert-required-elements
+If non-nil, automatically inserts required elements in the content
+of an inserted element.
+@end defopt
+
+@defopt sgml-omittag-transparent
+If non-nil, will show legal tags inside elements with omissible start-tags
+and legal tags beyond omissible end-tags.
+@end defopt
+
+@defopt sgml-tag-region-if-active
+If non-nil, the @samp{Insert tags} menu will tag a region if the region
+is considered active by emacs.  If nil, region must be active and
+@code{transient-mark-mode} must be on for the region to be tagged.
+@end defopt
+
+@defopt sgml-custom-markup
+Menu entries to be added to the Markup menu.  The value should be a list
+of lists of two strings.  The first string is the menu line and the
+second string is the text inserted when the menu item is selected.  The
+second string can contain a @samp{\r} where the cursor should be left.
+Also, if a selection is made according to the same rules as for the
+@kbd{S-mouse-1} menu, the selection is replaced with the second string
+and @samp{\r} is replaced with the selection.

+If you encounter something that you think is a bug, please report

+A test case that exhibits the bug, would also be useful.
+
+You can report a bug with the command @kbd{M-x sgml-submit-bug-report}.
+
+When PSGML needs contextual information it parses the document up to
+the point. During the parsing, it builds a parse tree.  The parse
+tree is used to initialize the next parse, to avoid having to parse
+things already parsed.  Changes to the buffer is supposed to prune
+the tree of all outdated information.  But if you get strange
+complaints from the parser, try and back up a bit and use @kbd{C-c
