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.
