I have not come across a case where it makes sense for a tree-valued parameter to have any default value other than the empty sequence. Defaulting it to a node in the principal source document, whether this is the root node or the outermost element, seems an odd thing to do. Michael Kay > -----Original Message----- > From: Karl J.
