fyi,
I created the taxonomy tModel in UBR [1] that I suggested above.

[2] is a DAML-S description of a Housing Agent service, then (using [1]) a 
UDDI categoryBag would look like this:

<categoryBag><keyedReference 
tModelKey="UUID:BF6770E0-1AC0-11D8-B8EF-000629DC0A53"
keyName="Housing Agent" 
keyValue="http://www.daml.ri.cmu.edu/ont/TaskModeler/HousingAgent.daml" />
</categoryBag>
