Otherwise cppuhelper::TypeManager::createTypeDescriptionEnumeration, sitting on
top such an AggregatingCursor, will miss any entities from provider P' in module
M if any previous provider P contains the same module M.

That happened when climaker generates cli_oootypes.dll, where the enumeration
missed everything from offapi in top-level module "com" because it had already
seen udkapi's "com", and only reported the handful of entities under offapi's
other top-level module "org" (which does not appear in udkapi).
