Sorry but I have yet to get very in depth with UDDI. This is probably obvious to most people but I can't find an answer elsewhere.
To clarify a bit:
What I want to know is if I wanted to store some extra data about some services (say ContactEmail), can I have a tModel for each service with a name Contact Email or are the tModels global to all services? Or are tModels global but the UUID element the global identifier?
