Re: Versioning and html[5] : application/xhtml+xml

Chris,

Re: http://lists.w3.org/Archives/Public/public-html/2007Apr/0612.html

I can understand why the IE team is loath to take actions that 'break
the web' in terms of backwards compatibility, quirks mode, etc.

My question is this:

1) IE7 will not render an xhtml document presented as application/xhtml+xml.
2) There is, therefore, nothing to break (it already doesn't work).
3) Given 1 and 2 above, is it feasible to support a 'clean' html[5]
when presented as application/xhtml+xml and preserve backwards
compatibility when presented with text/html?

There may be a very good reason why this is not feasible, of course,
but (to me) it has a feeling of some elegance.
