generate-qt3-test-set.xsl: examples with narrative results

[ChristianGruen]

With having looked at the details, I assume that example with narrative results should be excluded from the generated tests.

For example, a test is generated for system-properties()?#schema-aware (which is: true for a schema-aware processor, otherwise false.):

<test-case name="fo-test-fn-system-properties-002">
  <description>Test case for fn:system-properties</description>
  <created by="Michael Kay using generate-qt3-test-set.xsl" on="2026-03-31"/>
  <environment ref="global"/>
  <test>
    system-properties()?#schema-aware
  </test>
  <result>
    <assert>true()</assert>
  </result>
</test-case>

Generating the test is deliberate, it checks that the example is syntactically valid and doesn't throw a dynamic error.

The assertion

<assert>true()</assert>

is perhaps easily misread: it doesn't test that the result is true, rather it's an assertion that always passes if the expression result isn't an error. (Perhaps <assert-type>item()*</assert-type> would be clearer?)

I get it, thanks. Maybe exists(system-properties()?#schema-aware) ?
