         That is true, but it just does not make sense to include
DNS names in places where only IP (v4/v6/whatever) are required.

         Is it then reasonable to restrict the subtypes in the
DESCRIPTION clauses within the MPLS MIBs?

         The object is writable. It is also being used as a tertiary
index in a table, so the type of address is not necessarily known
a priori, so I don't think that this will work. I am open to
suggestions though. 8)
