Yes, and the same is for xhtml 1.0. For application/xhtml+xml you need the xml prolog and change of language must be like xml:Lang="xx". If served as text/html there is no need of xml prolog and change of language must be lang="xx" xml:Lang="xx". So at least xhtml is sgml-based in all cases, but if served as application is also xml-based. All depends of content-negotiation, see also w3c internationalization activity. This means also that we cannot apply two different criteria. ----- Messaggio originale ----- Da: "Neil Whiteley"<neil.whiteley@tag2.net> Inviato: 22/06/05 23.18.57 A: "Becky_Gibson@notesdev.ibm.com"<Becky_Gibson@notesdev.ibm.com> Cc: "w3c-wai-gl@w3.org"<w3c-wai-gl@w3.org> Oggetto: RE: Should validity be P1 or P2? (was RE: summary of resolutions from last 2 days) Hi Becky, <becky> To use XHTML 1.1 correctly it should be served as application/xhtml+xml which I can not do if I want to reach a majority of users. The W3C states that I should not serve XHTML 1.1[2] as text/html. So, perhaps my XHTML 1.1 can be made to pass validation with a customized DTD, but I'm still not really serving XHTML correctly according to the W3C. </becky> A lot depends on your interpretation of the document you refer to and specifically the meaning of *SHOULD NOT* used in the summaries table. The document "XHTML Media Types" specifically states that the terms used in the document are to be read and understood as stated in RFC2119. >From RFC2119: <snip> SHOULD NOT This phrase, or the phrase "NOT RECOMMENDED" mean that there may exist valid reasons in particular circumstances when the particular behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label. </snip> In other words you can serve XHTML 1.1 as text/html if you have good reason. I've had this conversation many times and I still can't convince many people even though it is clearly stated in the referenced documents.
