What I'm trying to do is have an XSD that enforces abstract patterns such as "All objects have an Id, Info and Status elements", by defining an abstract Obj composed of ObjId, ObjInfo and ObjStatus, and have Car be a restriction on Obj, CarId be a restriction of CarId, etc. Part of this problem is that some concrete Id can be complex, while others can be simple. Last, I cannot change these requirements as I am trying to represent and enforce these abstract patterns in an industry XSD (IFX) that currently does not. Guillaume
