professional relations (was: XFN usage stats and Re: [uf-discuss]rel="muse" implies romantic relationship?)

[Mike Schinkel]

As an aside, at the risk of starting a firestorm, it would be nice if there
were a way to let the user decide his one relationship, i.e. maybe

<a rel="custom:xxxx" href="...">John Smith</a>

Where "xxxx" is of course the person's one identifier.  Basically this would
allow people to create a folksonomy.  It could even require one of the other
predefined tags to ensure that aggregators can still get a rough idea.
