Is it really that indefensible? >So you are talking about "XHTML 1.0" served as "application/xhtml+xml" No, the start of the thread, which Bjoern joined was about XML conformance, and how Bloglines didn't follow XML conformance ruels. If you recall it was about a problem with an RSS XML document with broken encoding from http://www.webstandards.org/buzz/buzz.xml [1] which was parsed normally by Bloglines (albeit with wrongly interpreted characters) I was asking for help in how to ask Bloglines to obey the XML guidelines. Bjoern was just asking for similar help with XHTML guidelines. Arguments seem rather thin on the ground other than "well it works in both browsers so all is okay" which is something I can't agree with. For example I'm embarrassed that I can't show the W3's homepage on my pocket device, and I'm not embarrassed for it, it doesn't claim to render XHTML, the W3's own XHTML Appendix C guidelines state it won't be shown correctly. >You have the right to send "XHTML 1.0" as text/html. You only have the right if you follow the Appendix C. Guidelines, they are _not_ being followed by the W3 themselves, so are you saying the W3 homepage is wrong here? Or are you saying something else? >Here you are stressing out a problem of > - WCAG 1.0 > - Implementation of XML 1.0 in browsers. >not XHTML 1.0 I'm not stressing on any problem, I was asking a simple question about WCAG 1.0, and why it's appropriate to ignore the specificaition? I don't think it's appropriate to. >http://www.w3.org/TR/2004/WD-WCAG20-20041119/ > I don't see such requirements in WCAG 2.0 WD. That is a working draft, and has not been reviewed by a great many people, I think due to the poor responsiveness of W3 working groups whereby issues are only ever addressed at last call, many people, including myself, don't waste our time reviewing working drafts, I realise this isn't a good thing, but many year old issues against specifications just don't encourage it. >> The XHTML user agents are also extremely weak - lack of incremental >> rendering, bugs which cause valid documents to be marked invalid and >> error messages that only make sense to web-geeks displayed. >What is an "XHTML User Agent"? A user agent which claims to render XHTML - most XHTML user agents will also render a great many other content-types. >> By my understanding Mozilla, Opera, Safari, Konqueror, IceBrowser and >> huge numbers of mobile browsers all support XHTML 1.1, indeed I cannot >> think of a user agent that supports XHTML 1.0 that does not also support >> XHTML 1.1. >a) XHTML 1.1 application/xhtml+xml >b) XHTML 1.0 application/xhtml+xml >c) XHTML 1.0 text/html >Do you mean you don't know any user agents which does a) correctly and not >b) correctly? >So you are saying some user agents are unable to do a) and b) No, I'm saying that all that do b), also do a) - so XHTML 1.1 is as supported as XHTML 1.0 >Do you know a user agent which is unable to do c) ? Yes, Internet Explorer 6.0, I gave the file (with corrections) in the previous example. Or if you mean Appendix C documents, then yes, there are a number of XHTML only user agents, that do not attempt to render the text/html mime-type. Jim. [1] incidently the fixed encoding is now rather peculiar with things like <![CDATA[ Interview with Håkon Wium Lie ]]> which I believe whilst valid XML, is no longer the intended content as RSS user agents should not be expanding entities in title's.
