+* say RPM:Copyright without changing the namespace pointer to
+* something else can produce stale links. One way to do it is
+* to keep a reference counter but this doesn't work as soon

+* the existing namespace. The actual solution seems to add
+* a copy of the namespace at the top of the copied tree if
+* not available in the subtree.
+* Hence two functions, the public front-end call the inner ones
+* The argument "recursive" normally indicates a recursive copy
+* of the node with values 0 (no) and 1 (yes).  For XInclude,
+* however, we allow a value of 2 to indicate copy properties and
+* namespace info, but don't recurse on children.
