Description

There is currently one cache per interesting type, and entries can go into multiple caches.

Improvement 1: use List rather than Set; no way containment traversal can reach the same object twice.

Improvement 2: cache only in the leaf cache, and return values based on a list (of all possible derived caches) of iterators (for each element per cache).

When this is revisited it could usefully be re-used from QVTiModelManager.QVTiTypedModelInstance.getElementsOfType().
