XS:UNIQUE Question

XS:UNIQUE Question

XS:UNIQUE Question

I have an XML file that I would like to enforce uniqueness on a field.  I know I can use XS:UNIQUE to do this on fields within a type.  However, I want to do this on fields within a hierarchy.  So in the example XML, I want the tax rate field to be unique for a given customer, but each customer can have the same tax rate.  In the sample XML below, Customer # 123 and # 456 can both have a "1.2" tax rate, but customer # 456 cannot have two instances of the "1.2" tax rate.  If I try to put a uniqueness constraint on the tax rate, it applies it to the whole file, not just to one customer in the file.  I can't change the file format.  I'm just looking for a way to enforce uniqueness with an XSD given this format.  Thanks in advance for any help!
