Okay so here's where my confusion came in.

When I suggested that sequence idea, the thought was that root node + sequence is basically equivalent to (subordinate node name + parent node name) in that any participant should be able to tell whether a branch belonged to it or its descendants, and also should be adequate for filtering recovered XIDs.  But I'm not sure what you mean by "orphans" exactly - aren't all branches normally recovered by the root?  If so, does the subordinate path actually matter?
