           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
           those features.

        -- 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.
        -->

<!ENTITY % HTML.Highlighting "INCLUDE"
        -- Use this feature test entity to validate that a
           document uses no highlighting tags, which may be

           contains no forms, which may not be supported in minimal

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

<!ENTITY % Content-Type "CDATA"

        -->

<!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 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.
