That is not a problem case - that is *exactly* the case that makes
class="url" necessary.

Incorrect .........................................^^^...................^^^

Applying class="url" means selecting that "very special" URL to be *a* URL
for the hCard.

Please re-read what I wrote above.  *A* URL.  There is no assertion of
uniqueness ("the").

No.  It means this is *a* value for the "url" property.

The other URLs are not values for the "url" property.

Correct in that it expresses that that "special" URL is a value for the
"url" property.

No - you added the word "special" and then claim it as a conclusion.  That
is a tautology.

There is currently no way to express that semantic in hCard, nor in vCard
for that matter.

No, the microformat class name "url" has the semantics of the "url" property
as defined in vCard and iCalendar.  See the hCard profile which defines the
class name "url": http://microformats.org/wiki/hcard-profile

No.  The microformats class name "url" specifies that *that* URL is *a*
value for the "url" property of the hCard.  That is all.

Where does W3C define "url" to mean what you say?
