MemSchemaPermissionDel
synchronize schema when a *_permission relation has been deleted from a group

MemSchemaSpecializesAdd

MemSchemaSpecializesDel

DelCWETypeHook
before deleting a CWEType entity: * check that we don't remove a core entity type * cascade to delete related CWAttribute and CWRelation entities * instantiate an operation to delete the entity type on commit
