Re: Update on RDF in XHTML

Hi Joseph (and thanks your feedback and continuous feeding of this

That remains to be seen indeed, but the possibilities that such a system
would offer (basically allowing to integrate a fair number of XHTML
documents in the Semantic Web space) makes me hopeful in that regard. In
any case, should this document be continued, that's probably the 1st
item we'll ask feedback on.

HTML 4.01 (and by inheritance, XHTML 1.0) allows more than one profile:
"""
profile = uri [CT]
This attribute specifies the location of one or more meta data profiles,
separated by white space. For future extensions, user agents should
consider the value to be a list even though this specification only
considers the first URI to be significant. Profiles are discussed below
in the section on meta data.
""" http://www.w3.org/TR/html401/struct/global.html#adef-profile

XHTML 1.1 (through XHTML Modularization) only allows one, by setting the
type of the profile attribute to "URI" instead of "URIs", although this
might be more a bug than an intended change. Probably something worth
checking with the HTML WG.

Could you clarify what you mean by not grabing?

I would also favor only 1.0 for now; we can still come up with a new rel
value for the next versions of XSLT if needed.
