Hi,

I would like to construct a vector-valued finite element space where the 
components may be related to each other on the boundary.

Example:

   Let P1 be piecewise linears on K.
   I want the subspace {(u, v) \in P1 x P1 such that u = v on the 
boundary of K.}

Is this possible in DOLFIN today?

Thanks!
