XSLT is a hammer from an alternate universe where the fundamental  
particle of matter is the thumb :-P

In most cases, there is a Class whose instances correspond to the  
Things which would be mentioned in a Doculope* labeled with a Concept;  
however the Concepts and the Classes usually want to be different  
entities, and the mapping seem to be easier to describe in SWRL-DL  
rather than OWL.  This is a situation where distinguishing BTG and BTP  
separately helps a lot.   BTI can be handled trivially using roles, as  
long as the end point of the chain is Object, not Data.

I've been trying this for KOSS (using Attempto Controlled English) to  
try and get more precise semantics for precombined and subdivided LCSH  
headings. Things seem to make more sense if you treat the inferred A- 
box as a T-box for an actual ontology.  This makes a lot of sense if  
you treat the domain of interpretation of SKOS as the Doculopes, not  
the underlying Things.

* Doculopes are documents a la Buckland.
