profile-uris

In hcalendar-issues, it is ACCEPTED that each microformat should have a profile URI, like [the XFN profile].

Some issues include:

 * what domain to use? Candidates include:
   * www.w3.org (see )
   * xmdp.org
   * microformats.org
 * what about versioning? how to keep in sync with the wiki and test materials?
 * what profile URI to use for combinations, such as hcard and hcalendar?

One proposal is: use www.w3.org, following W3C namespace policy. For example: an hCard Profile at w3.org, and discussion: an hCard profile that seems to work with GRDDL.
