I remember reading something about how the indexes are temporary.  I was 
under the impression
that they would go away and be re-created as needed?

I can detect if one of these elements is not in the new ElementTree, but, how 
do I get the info needed
to call beginRemoveRows( QModelIndex parent, int row, int col).  I can get the

but how can I get the deleted items parent QModelIndex?

Well, you have to have some mapping from Element back to a proper index,
i.e. you need a way to get the index for an Element in the tree. Then
you can call parent() on that index.
