Well, that's good then.  I did say we didn't support it.
Delete the @attrset bib1 out of the above though, and we still don't 
support it, due to the floating @attr 3=3 at the beginning.

And yes, I do still call it PQF, much the same way that you allow title = 
(foo or bar) in CQL and still call it CQL ;)
