ISSUE-55: Re-enable @profile in HTML5 (draft 1)

From: Manu Sporny <msporny@digitalbazaar.com>

Message-ID: <4ABFFD4C.2000508@digitalbazaar.com>
To: HTMLWG WG <public-html@w3.org>
I volunteered for an action to produce a draft document that included
@profile in HTML5:

http://www.w3.org/html/wg/tracker/actions/144

The document attempts to address the long standing ISSUE-55:

http://www.w3.org/html/wg/tracker/issues/55

After speaking with Julian over the weekend, we explored the possibility
that perhaps the document should focus on the concept of extending
processing behavior for user agents via @profile and @version. Perhaps
even stating that we'd like to move away from @profile (because it
hasn't been used as much as we'd like), toward something that is simpler
and has been used in both XHTML and RDFa: a specifically formatted
@version attribute.

We also wanted to provide backwards compatability for GRDDL,
Microformats, DC-HTML and other applications of @profile on HEAD. The
HTML+RDFa spec was already defining @version and @profile, so I moved
them out of that spec and into a separate document of their own, per
advice given on the HTML WG telecon two weeks ago.

This is a very rough conceptual draft and thus we could end up adopting
all of it or none of it. It attempts to find a delicate balance between
the advice given via the HTML WG, WHAT WG, and RDFa TF:

I expect that there will be arguments around these concepts:

1. Whether or not we should make @profile obsolete but conforming (this
   draft does that, as does the base HTML5 specification). We don't have
   to obsolete it, though I think it would be a good idea.
2. Whether or not we should depend on <link rel="profile" href="..."
   to specify profile relationships to the current document. GRDDL
   and Microformats depend on either this or #1.
3. Whether or not we should obsolete @version. RDFa would like to keep
   @version.
4. Whether or not we should adopt a new markup format for @version in
   order to make language design easier in the future while also making
   it easier for authors. This may address WHAT WG's issue with
   @version.
5. Whether or not the world would be a better place if Kanye West never
   rose to fame.

Feedback on the direction of the draft would be great. Fire away! *ducks*
