DuplicateDescendantNameError
Duplicate descendant name for node type.
Changing the node name or the parent of this node as requested would
result in a (new) ancestor of this node having two descendants of the
same type with the same name. This is only a problem if this ancestor
maintains a dictionary of the descendants of this type.
Note that after this exception has happened, the tree is in an
inconsistent state.
