The "HTML 5: The Markup Language" draft already takes the approach stating stricter requirements where needed. It doesn't confine its definition of "conformant document" to only what can be expressed in the content-model sections. It contains other sections that state additional constraints; for example: http://www.w3.org/html/wg/markup-spec/#noscript-constraints http://www.w3.org/html/wg/markup-spec/#meta.charset-constraints http://www.w3.org/html/wg/markup-spec/#meta.name-constraints http://www.w3.org/html/wg/markup-spec/#meta.http-equiv.content-type-constraints There are quite a few more of those that I still need to add, but they'll all get added eventually. --Mike -- Michael(tm) Smith http://people.w3.org/mike/Received on Monday, 26 January 2009 23:22:29 UTC
