Thanks Dan.

The original idea was that a scheme has several skos:hasTopConcept
properties, pointing to the top level concepts for that scheme (i.e. so not
functional).

If we made skos:hasTopConcept functional, each scheme would have to be
defined with a single root concept ... do you think it's worth doing it that
way?
