Subject: Re: [ubl-dev] Test Assertions for UBL Calculation Model?
The other advantage of using XPath ... [ like one starting doc("http://docs.oasis-open.org/ubl/...")/... to say something about the schema (e.g. to extract a dictionary entry name if you really need one) or doc($instance)/Invoice/... to assert something about the invoice (where another reference defines $instance), e.g. using a variable assignment element of the xpath-profile test assertion ] ... is that you can make the assertion(s) executable. You can perhaps convert to Schematron for individual assertions or if you want to chain the assertions (make one dependant on the outcome of testing an invoice according to another) you can (eventually) use a test assertion xpath profile execution engine. For the latter you may need to wait for tools to be in production or write your own but WS-I is doing the latter quite successfully and I hope there will be tools soon, perhaps some free ones. The Balisage 2009 XML conference will feature a presentation on this by Jacques Durand of Fujitsu US / WS-I / OASIS (TAG Chair, TAB, etc) which should be excellent (plus Ken and I both get a mention!).
