Is there a consistency expression for MonetaryTotal objects

[David Goodenough <david.goodenough@broadwellmanor.co.uk>]

Presumably there exists a rule that can be used to validate arithmetically a MonetaryTotal object. Then for an Invoice/Order/RemittanceAdvice rules like the sum of the line items should equal the totals. And I am sure there are other testable consistency rules.

 

Are they documented anywhere? If not has anyone come up with any rules of their own that are useful?
