Alaric,

Oh yes - RDF is a different animal indeed!

However - CAM <ContentReferences> do this mix-n-match for you very 
neatly without incurring the overhead of RDF - very simply using an 
Alias mechanism.  So you can create an Alias that points to a particular 
registry domain - eg : USPS - Addressing registry run do US Postal, and 
say OAGi - ERP system registry run by Open Application Group.  Now you 
simply associate the correct definition to the domain registry.  And 
include structure components into your XML transaction accordingly.

Unlike namespaces these registries are 'live' and can actual return you 
noun definitions and more - that can be used by processors such as jCAM.

Or of course - you can simply 'consume' the semantic facts in the CAM 
template 'as is' and use this to do reasoning - crosswalking - etc, on 
your own in your own software components.

Cheers, DW.
