A MCR.Component.MetsMods.Generator creates the structMap[@TYPE='LOGICAL'] as noted in
with mets:mptr elements to the mets files of the children/parents of the rendered mcrobject.
The mets editor does not properly handle those elements. It removes the labels and does not recognize the already set type furthermore it removes the contained mets:mptr element.
Maybe it should just ignore but retain mets:div elements which are having a child mets:mptr element. In
one can see the result (the type attributes were initally unset)
