I thought we had decided that the copy property could include
information about when it was copied. Thus the property wouldn't need
to be deleted, it could live indefinitely. (I.e.), Property says
something like revision 11.2 of this node is a copy of revision 12.3.

Then the property itself distinguishes which revision the copy occurred

Am I missing something?
