Sam, I disagree.

I did mention how there is a serious disconnect between HTML 4 and
HTML 5 when it comes to "conformance", and how conformance is meant to
be interpreted by HTML authors/editors, and user agents. I mentioned
the disconnect between many times the user agent is also and author,
with a shared API/data model.

We also ran into problems with the so-called "use cases" with RDFa. It
would seem that no use case was sufficient. This one was too long,
this one was too short, and so on. When we asked for examples of what
makes a good use case, we were given a basic shoulder shrug.

"I dunno. I guess I'll see it when I see it."

As for reason -- this group can't even agree on what to put in the
Best Practices document. Why? Because the so-called "best practices"
have been applied erratically, and, again, more to justify personal
opinion and biases. The number one justification to wall HTML5 off
from RDFa is Henri's repeated references to the best practices as
"rules", yet we've had Ian say these are really more guidelines than

You're saying that all of this takes precedence over the advice given
by experts in the field, as well as other W3C groups chartered to
provide recommendations and advice...this counter to the very charter
that supposedly forms the basis for this group.

Seems to me that this working group's underlying practice is more to
take the path of least resistance, than to create a new version of
HTML that meets the needs of all people, not just a small group
remarkable for the lack of diversity of its members.
