Getting constraints to work

When using vellum constraints I'm having some difficulty getting constraints to work, especially with the connectAdjacentpieces SOP (Adjacent Pieces from points).  The connectAdjacentPieces SOP is bringing in an attribute by means of the piece attribute which is a custom attribute I created, but I don't see any connectivity between the points ?

Vellum constraints are using default points from the vellum object in order to describe themselves to the solver. Check the vellum constraint node : no matter how many constraints are created, point count is the same - there are only new primitives created. Connect Adjacent Pieces on the other hand may or may not change the point count depending of the type of connection. From the three methods only Adjacent Points could be used with Vellum.

Therefore there is no need to use vellum strictly within a DOPNetwork; when using the vellumconstraints_grain SOP, correct ? 

One must use the connectAdjacentpieces SOP with vellum ? I may be doing something wrong, I created an attribute, promoted that attribute from points to primitives but the connectAdjacentPieces is not picking up the attribute when the attribute is given in the Piece Attribute field ?
