Indeed. I think I mentioned that Schematron tests can be lossy: the
assertion *text* would state the normative constraint in plain language,
the assert *test* will implement the test to whatever extent practical.*
So a statement like "you cannot test for prime in XPath1" has an implicit
"with no false positives" which is true; but for Schematron the relevant
issue is "with no false negatives" which is certainly untrue for XPath 1.
