I think we may have a problem in saying that we'll name global 
attributes like local attributes, since we say we'll name local 
attributes as if they were elements, and (except for top-level elements) 
these are named as properties of an object class.  Just like top-level 
elements, global elements nominally don't have an object class.

I don't think it would be *hard* to figure out names for global 
attributes, but our naming advice so far is insufficient to explain how 
to do it.

Regarding UidAttributeGroup, that's certainly a convenient way to 
organize global attributes, and we should probably add a rule about 
this.  Another option, I suppose, would be to have a UBL ur-type from 
which every other complex type derives, and put the attributes on that. 
  But doing this may have unintended consequences or make things ugly.
