If this can help, also in FAO we are specialising the RT relationships of the
AGROVOC thesaurus, and we have adopted similar approach: to create a
hierarchical tree of relationships, in top of which there is the traditional
RT (skos:related).
Attached a screenshot of the organized relationships.

If needed I can provide a document describing our approach.

Hi Dale, Bernard,

I support Bernard's proposal. this is how I would have done it, also. The
SKOS Primer we're working on now (first bake in coming days!) has a 
small section which encourages that kind of specialization of the SKOS 



PS: and a happy new year to all of you :-)
