If you trawl through the semweb side of W3C's house, you'll see the 
second broadly defined, for some definition of meaningful. By the 
end of the year the W3C will have signed off on the specs. It is an 
alternative approach. Though perhaps the most interesting (and 
underappreciated) option out there is FIPA's, which seems to sit 
somewhere in the middle of the two.

That's straightforward enough. Before we move past that permathread, 
either some existing architectural constraints need loosening or the 
20,000ft view needs to explicitly acknowledge a resolution layer. In 
any case details of URIs are not stopping the higher level semweb 
stuff being worked on (at that level everyone agrees that a URI 
names a something), it's an engineering issue mainly.

Other than entities, I have very few problems when I stay inside XML 
1.0 and a vanilla parser. It's the extraneous stuff (starting with 
Namespaces) and the odd dissonant API call that tends to bite.

It was never abstract, not in a world where you have consume other 
people's data as well as produce it. Too many people think base 
interoperation starts with object models and type systems instead of 
protocols and syntax.
