Speaking only for Reuters and the IPTC, we are dealing with 
taxonomies, and very much intend to treat the left part as 
a URI representing the taxonomy, and the left and right 
parts together as representing a term in the taxonomy.  We 
intend that these URIs be dereferencable and that they be 
usable for constructing RDF triples.  Indeed, we have 
provided an XSLT transform which converts a subset of 
NewsML 2 metadata to N3.  Hence, we do perceive our use of 
CURIEs as representing namespaces, and terms in these 
namespaces.

I should add, in order to get all the heretical stuff out 
in the open, that we have no intention of using xmlns 
declarations to associate the left side with a URI.  So we 
most definitely do not perceive CURIEs (as used by us) as 
representing XML namespaces.
