   RE: [xml-dev] Article: Keeping pace with James Clark

Sounds good in theory and in the REC, but the 
insistence that URIs be dereferenceable makes 
it inconsistent in practice.

Yes, they are. Neither Infoset nor namespaces actually assigns any 
semantics to anything. Namespaces is sometimes used by local 
processes to assign semantics to particular elements in particular 
namespaces, but namespaces itself is just more syntax. The infoset 
assigns only the most bare bones semantics. Essentially it just 
defines another way of looking at XML. Only xml:base could arguably 
be claimed to be at the semantic level, and even that is less 
semantic than xml:lang.
