Thanks.  If that is legitimate, it seems the most straightforward thing to do.

If anyone knows of a reason this wouldn't work, please chime in.

Only half an answer here, I'm afraid:

I note that skos:Collection is an instance of owl:Class, so it should be a
legitimate value for an rdf:type or rdfs:range property.

But what I'm not seeing is a formal indication of what are the instances of a
skos:Collection class, but a plausible guess would be all the skos:Concept
values of skos:member for that collection (possibly together with all the
instances of the skos:Collection values of skos:member's of the collection).  If
this is the case, then it seems that rdfs:range would have the effect you desire.

Values will be associated with the individual description elements, where some of values should be constrained by other controlled vocabularies. For example, my description set contains (length, weight, color) and color is to be constrained to (red, yellow, blue).
