Maybe the problem is that we're trying to point to an authoratative
hCard when in reality what we want to do is simply (like you just
said) point to a more detailed hCard. That way, if you have a
professional hCard set up on your work site you might want to point to
that from your conference listing page, but if you have a personal one
set up as well you might want to point to IT from a personal site
somewhere. Managing "authoritative" relationships between cards seems
to be more hassle than it's worth. Simply pointing to a more detailed
card could be the solution.

So for example, the rule could simply be that the anchor with
class="url" found inside the hCard will point to a more detailed hCard
should it have a direct reference to an ID. In other words the
following example would be pointing to a more detailed hCard:

<span class="vCard"><a href="http://johnfallsopp.com/about/#myInfo" class="url
fn">John Allsopp</a>

The moment the ID is provided, it indicates that the link isn't just
pointing to any old resource on the web, but that it is in fact
pointing to a more detailed hCard.

The only problem that I can see with this model is that you might not
want your hyperlink dropping to the hCard's location when it's
