can you say how you think that should work? At the moment we have an internal (extensional) value-set mechanism but I assume you are proposing an alternative way of doing it?
Well, think it as an alternative to referencing value sets from URI (in the sense of having only one binding), but the binding produces a set of terms when processed (as uris)
Ok so you are saying you want to be able to put IHTSDO expression syntax expressions into archetypes directly? I would suggest a dedicated PR for that - I can't see one there for it. This CR I think just wants to achieve a basic thing - correct format (according to IHTSDO) basic URIs.
