     In case 'op_depth' is greater than 0, this is part of a layer of
     working nodes; in that case, the following presence values apply:

     Only allowed values: normal, not-present, incomplete, base-deleted,
     excluded.  (the others do not make sense for the WORKING tree)

     normal: this node has been added/copied/moved-here. There may be an
       underlying BASE node at this location, implying this is a replace.
