Schemas

-- ==================================================================
-- 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.
