-- MODIFICATIONS FOR IFC VERSION SUPPORT
--
-- Between IFC editions, BuildingSmart removed or changed definitions
-- that were used by some systems. We retain some old entities and
-- relax certain typing to support legacy data. These changes are all
-- clearly marked by "LEGACY". Retained definitions are at the end.
-- Keep schema name IFC4 for convenience of existing applications.
-- You can force a specific schema name by setting the schema type, if
-- desired. Also renamed in EXPRESS typeof() statements below.
