W3C HTML validator has very poor validation of attributes and is technically unable to check this case. The HTML DTD however defines <code>profile</code> attribute as <code>%URI</code> (it's alias for <code>CDATA</code>), same as <code>&lt;a href&gtl</code> attribute.

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:
    • microformats.org
    • www.w3.org
    • xmdp.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?
    • note HTML4.01 states "that one or more meta data profiles, [are] separated by white space"; though it's simpler for authors if they can just use one profile URI.
  • More profiles are needed.

One proposal is: use www.w3.org, following W3C namespace policy. As to versioning, change the profile whenever the wiki changes (within some reasonable latency, say, a couple weeks or a month). For example: an hCard Profile at w3.org, and discussion: an hCard profile that seems to work with GRDDL.

Existing profile URIs

Combined Profile

The following URL covers all non-draft Microformats as of March 2008, except XMDP and XOXO. You can mix and match it with other XMDP profiles for new/draft microformats.

Validator warning

Due to inconsistent wording of the HTML specs, HTMLTidy (and other tools?) give "Warning: <head> escaping malformed URI reference" when more than one profile is used, e.g. 

<head profile="http://www.ietf.org/rfc/rfc2731.txt http://www.w3.org/2006/03/hcard">

W3C HTML validator has very poor validation of attributes and is technically unable to check this case. The HTML DTD however defines profile attribute as %URI (it's an alias for CDATA), same as <a href> attribute.
