thank you very much for your comments.
David, what concerns the testing of XDM values, I first did not see the
connection to the Java scenario, but finally I did see it: Java systems
producing XML documents usually also process them, and it goes without saying
that such processing is a good candidate for XQuery called from Java; and as
XQuery produces by definition XDM values, we do have a need to tackle XDM values
in unit tests.
Michael, your report on the testing via XPath assertions against the query
result is interesting and comes very close to what I imagined. I have not yet
understood if the tool launching the tests and evaluating the results according
to the test configuration you showed is an official W3C testing tool, an
internal Saxonica tool, or perhaps neither of them.
"Your situation, of testing XML documents, is essentially the same
problem except that the query is always "." and the variability is in
the source document it applies to...."
But I think that the query is not "." - rather, the queries in my case are
simply the queries expressing those assertions. So it is a 1:1 situation what
concerns the processing, the only difference is in the interpretation: an error
in your case means the XPath evaluator failed, in mine it means the input
document is not as expected.
Final note: I wonder if there is a rationale behind confining assertions to
XPath expressions, rather than the more general alternative - XQuery
