From: "Dr. Brendan Patrick Mahony" <brendan.mahony@dsto.defence.gov.au>
I am trying to do some theorems about inducing lattice structure on
subsets of partial orders.

I have a theorem, sub_po, that the order relation forms a partial
order when restricted to the subset. I would like resolve sub_po
against various theorems in the partial_order locale, in particular
theorems from parent locales. If I make an interpretation using
sub_po, all these become available, but all my partial_order notation
become ambiguous (copies for parent order and sub-order).

Is there any way to make an interpretation without bringing in the
notation?

Does the mysterious "structure" mechanism have any use here? (Is it
explained anywhere?)

If I don't make an interpretation, how can I get at parent locale
theorems without restating and reproving the parent locale results?
