<!--================== Feature Test Entities ==============================-->

<!ENTITY % HTML.Recommended "IGNORE"
	-- Certain features of the language are necessary for compatibility
	   with widespread usage, but they may compromise the structural
	   integrity of a document. This feature test entity enables
	   a more prescriptive document type definition that eliminates
	   the above features.
	-->

<![ %HTML.Recommended [
	<!ENTITY % HTML.Deprecated "IGNORE">
]]>

<!ENTITY % HTML.Deprecated "INCLUDE"
	-- Certain features of the language are necessary for compatibility
	   with earlier versions of the specification, but they tend
	   to be used an implemented inconsistently, and their use is
	   deprecated. This feature test entity enables a document type
	   definition that eliminates these features.

<!--================== Imported Names =====================================-->

<!ENTITY % Content-Type "CDATA"
	-- meaning a MIME content type, as per RFC1521
	-->

<!ENTITY % HTTP-Method "GET | POST"
	-- as per HTTP specification
	-->

<!ENTITY % URI "CDATA"
        -- The term URI means a CDATA attribute
           whose value is a Uniform Resource Identifier,
           as defined by 
	"Universal Resource Identifiers" by Tim Berners-Lee
	aka http://info.cern.ch/hypertext/WWW/Addressing/URL/URI_Overview.html
	aka RFC 1630

	Note that CDATA attributes are limited by the LITLEN
	capacity (1024 in the current version of html.decl),
	so that URIs in HTML have a bounded length.
