Re: Comment on Test Assertion Markup Language

[Stephen Green <stephengreenubl@gmail.com>]

Following up on this, although I hope to produce
better artefacts a bit later (with some help with the
XPaths and TAML) I'll send a more intact, though
incomplete, set of test assertions which go some 
way to defining an example subset of UBL (loosely

based on the incomplete UBL 2 SBS for an invoice).

I'll attach a zip file but copy TAs inline below too in
case there are any problems sending attachments.
Note that it starts with mandatory TAs for elements

mandatory in the standard UBL 2 invoice, then it
has 'permitted' parts of the subset, then finally TAs
with negated predicates for elements outside the subset
with 'preferred' prescription (to say it is preferred that

those particular elements and attributes are not in the
invoice).

I anticipate this set of test assertions changing/being
corrected but I hope it will inspire some similar use to
support definitions of subsets like this.

Best regards

Steve
