I'm trying to find a way to handle multiple versions of an element definition within a single schema. I keep running into UPA problems (among others) so I was wondering if anyone has solved this problem. I want to allow a single schema to validate instance documents like <root> <a version="1.0"> ... some complex content </a> </root> or <root> <a version="2.0"> ... complex content but different from version 1.0 in some way </a> </root> I have tried defining two groups, a10 and a20, that each have a fixed value of attribute version. These are then listed in the schema under <root> within a choice element. How can I make this work? It seems as if it is an important situation. Thanks, Paul
