Some feedback from the use of such a system 'in the wild'. We do not
make use of broaderTransitive in our system.

In our search engine for cultural heritage items, we give the user the
choice when doing a search for items using an item from the
classification system.
The user can choose to retrieve documents for which there is an exact
match on the specified classification item, or by checking a box also
retrieve documents that implicitly have been classified with items
that lie on the 'path' along the hierarchy to the root.
