Off point.  The proposal does not involve xml data islands in text/html.

It is simply to have to have the new HTTP content-type header value

   Content-type: text/html; profile=xhtml

as an alternative to various other choices including:

                 application/xhtml+xml
                 text/xml
                 application/xml

for valid, functioning XHTML documents.

The difference is that many extant user agents will not (and should
not) attempt any rendering of the last three.

There are various sensible ways that a content provider might make
use of this option.

The proposal is not intended to suggest that "text/html; profile=xhtml"
is suitable for every XHTML document.
