OK.  Here's a related question, I need to check that my weakly enforced 
Dirichlet BCs are being properly handled.  Right now I think I need to 
sample the discontinuous function along a given subset of the boundary 
(which I do by iterating through all the vertices and selected solution 
components by position), and manually integrate those values along the 
boundary for comparison with the prescribed value, say zero for 
simplicity.  Is there a better way to do this?  I am observing some 
noise (oscillations) in the projected solution near the boundaries and I 
am trying to figure out why.
