I hope you don't mind if I add a small note to this, so that people
can see where Niklas' original suggestion went to. (It might look like
it has dropped off the map.)

The suggestion that we didn't need to be bound to the XHTML namespace
for our URI mappings came from Niklas. He suggested that we add the
word 'relations' to the current XHTML namespace, to indicate more
clearly that we were dealing with a vocabulary of link types. I think
most people thought that it was a good idea, so I took the action to
raise the issue on the XHTML 2 call to see if anyone had any

That group _also_ thought it was a good idea, but then both Roland and
Shane pointed out an important point, which was that whatever we did
had to harmonise with @role. (The technical reason is that if RDFa and
@role were to use different URI mappings then they wouldn't be able to
share any defaulting mechanism that we might devise, such as 'no
prefix'.) Also, since the @role taxonomy defines types rather than
relationships we felt that making them share the name 'relations'
wasn't ideal.

Which is how we ended up with 'vocab'. :)

Sorry for the long explanation, but I just wanted to clarify that
Niklas' idea was essentially sound, but that it had to be tweaked a
little to fit with other initiatives, such as @role.
