No, that is right. But currently only the highest dimension (DIM)
elements can be partitioned. This information is then propagated to to
the next lowest dimension elements (DIM-1) but only for those that are
on the boundary of the domain. The partition number is not stored
internally for vertices (and note that it would be ambiguous because a
vertex could straddle two or more partitions).
So for a 2-D mesh, surface labels will all have a partition number, and
otherwise, only edge labels *on the domain boundary* will have a
meaningful partition number.
