Sorry for the late entry into this discussion, and if I've missed something, 
I apologize.

Having read [2], I am a bit concerned about the requirement and assumption 
that semantically similar (or even identical) properties should affect 
elements in a different namespace.

For starters, the requirement that (the world over) all properties intended 
to affect font-family should be named that seems a bit much to ask.

Second, it seems prone to accidental overlap.  If (when) namespacing becomes 
mainstream, it may be that NS1:foo and NS2:foo are completely different 
concepts, yet NS2 element behavior may be affected by the accident that it 
is contained by a NS1 element.

Third, it may be that there is not a direct mapping from one property to 
another, yet the two are related.  In this case, it would be nice to be able 
to have some expressive power for determining the mapping.

I know it's a bit presumptuous (me being an unknown), but perhaps it would 
be good to have a framework of some sort to allow mapping between different 
vocabularies, which could be referenced from a particular document using the 
arbitrary namespaces.

The framework could start off simple, with a simple syntax for mapping NS1 
properties to NS2 properties.  Later, it could be expanded to be expressive, 
such that the NS1 property foo maps to NS2 property bar if (some 
expression).

I hope I've been helpful.  It is possile that you've already considered this 
idea, and have decided it's not worth the complication.
