Hi Graham,

Fair enough, but could you also comment on my earlier point about introspection?

Yes, constraints on variants expressed using TMQL can be used for validation.
But can a schema based on TMQL serve as the basis for a forms-based editing
interface like Ontopoly?

Is it not the case that constraints expressed in TMCL are by definition easier
to introspect?

Do you see the problem I am concerned about?
