David,

By schema profile they mean defining subset of XML Schema spec and 
specific contraints on use of XML Schema in order to improve 
interoperability. I do not think that CAM is suited for that task. No 
technology solution is. What is needed a a profile spec that describes 
the constraints on and subset of XML Schema.
