1 <!SGML "ISO 8879:1986"
2 --
3 Document Type Definition for the HyperText Markup Language Plus
4 for use with the World Wide Web application (HTML+ DTD).
5 This DTD is designed for use with SGML authoring tools and
6 it is expected that most browsers will tolerate omissions,
7 in particular, missing <DIVn> elements and <P> start tags
8 following headers, which can easily be inferred from the context.
9
10 The HTML+ DTD which is structured as an HTML core plus a
11 number of additional modules which can be included by an
12 entity definition in a document's <!DOCTYPE> element.
13 You can include specific features in your document
14 using the DOCTYPE declaration at the start, e.g.
15
16 <!DOCTYPE htmlplus [
17 <!ENTITY % HTML.tables "INCLUDE">
18 <!ENTITY % HTML.forms "INCLUDE">
19 ]>
20
21 This spec also allows for authors to extend the DTD and
22 to define how any new elements are rendered in terms of
23 existing ones. This should be used with caution.
24
25 I would like to acknowledge the influence of the TEI DTDs
26 which proved very helpful in restructuring the DTD.

30 Changes:
31
32 Added align attribute to headers with same values
33 and meaning as for paragraphs.
34
35 Added prologue and epilogue elements and fixed bug
36 in definition of %paras with HTML.emph.
37
38 Added entity names for standard icons c/o Bert Bos.
39 This are enabled with the HTML.icons switch.
40
41 Added PRE to content model for LI and DD, and changed
42 DL to require at least one DT per DD. Math is now
43 part of %text; but can't be nested.
44
45 Tried to permit an optional epilogue following last
46 division, but sgmls gave: Content model is ambiguous
47
48 Added support for graphical menus to SELECT/OPTION.
49
50 Liberalised content model for headers to %text;
51 Added optional NOFOLD attribute to P element to
52 inhibit SGML folding of whitespace.
53
54 Dropped the LIT element and changed the TAB element
55 over to the LaTeX model. Added NOWRAP to P element.
56 Replaced TH/TD's align=numeric with ALIGNON="." etc.
57
58 Made anchor NAME attribute conditional on HTML.obsolete
59 Added HTML.obsolete for obsoleted HTML elements
60
61 Added SIG attribute to A and LINK for specifying
62 a digital signature to attest that a linked document
63 is unchanged.
64
65 SRC attribute added to NOTE to allow authors to override
66 the default icon chosen on the basis of the ROLE attribute.
67
68 Switched REL/REV back to CDATA to avoid trouble with duplicate
69 name or name token error. Using an explicit list of relationship
70 types would force us to drop REV.
71
72 Added top/bottom alignment attribute to CAPTION
73
74 REL and REV domains now defined by parameter entities
75
76 SRC attribute added to LINK to allow images to be used
77 in document specific toolbar
78
79 Baseline attribute added to FIG and IMG to give precise
80 control of vertical position relative to baseline.
81
82 Revised comments for <A> and <LINK> to remove references to
83 obsoleted timing attributes and to add a list of "standard"
84 relationship types.
85
86 CHANGED element now uses more meaningful attribute names.
87
88 STATE dropped in favor of INPUT with TYPE="hidden". Forms now
89 support a link to a script for client-side execution of constraints.
90
91 The element definition for DIV1..DIV6 and P no longer permit the
92 start tag to be omitted. This was regrettably forced by a
93 restriction in the SGML standard. Browsers *must* be capable of
94 inferring them when missing,in order to cope with legacy documents.
95
96 Fixed some errors in earlier version to do with start tags and
97 definitions of parameter entities. The content model for FIG has
98 been changed to use a P element for text to avoid an SGML parsing
99 problem with a line break before the caption.
