Re: Last Call Response to ISSUE-73: RDFa Profile management

Sigh, I feel like a ping-pong ball.

Looking at the latest drafts

- I see the sentence you describe below listed in the RDFa Core document (which is fine with me, b.t.w.)
- Looking at the XHTML+RDFa version, under section 5.2, it says:

[[[
This specification provides a default RDFa Profile. It is available at http://www.w3.org/profile/html-rdfa-1.1.
]]]

(as an aside: why is this section non-normative?)

This means that, when processing XHTML, a processor must not refer to the the /profile/rdfa-1.1 one, because that is the XML profile. Putting it another way, in order to work properly, the content of rdfa-1.1 (the bunch of prefixes) should be added to the html-rdfa-1.1. This is not what I said in 

http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Feb/0182.html

and what Manu agreed with in 

http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Feb/0184.html

and which was a reaction on Manu's mail in 

http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Feb/0180.html

which was accepted by Shane in 

http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Feb/0181.html

So where are we now? We should either say in the XHTML+RDFa document that the XHTML includes _both_ profiles (which is allowed per the text you propose), or we have to agree that the effective profile files would duplicate content.
