Saxon

I think this is dead code. The method unavailableInXX is used only when the -XX option to the test driver is used, and this option dates from when we had a version of the XX compiler that could be invoked from Java (with the Javascript parts, that is, the XPath parser) running under Nashorn. It also reflects the fact that at that time, SaxonJS didn't support higher-order functions.

We should probably get rid of this code now, because I doubt we will ever reinstate the ability to run the XX compiler from Java.

But it's true that the HE test driver isn't running HOF tests. This is because Xslt30TestDriverHE at line 1242 has

needsEE.add("feature/higher_order_functions");

which is wrong and should be deleted.

I can confirm that if we change this, the tests run and (for those I've tested) they all pass.

QT3TestDriverHE has the same problem: lines 282-3 read

           } else if ("higherOrderFunctions".equals(value)) {
                return (edition.equals("PE") || edition.equals("EE")) ^ inverse;

which needs to change to:

            } else if ("higherOrderFunctions".equals(value)) {
                return !inverse;

Fixed error-3175a with a change to the way the test driver handles the dynamic_evaluation dependency.

The same change also fixes system-property-014b.

Fixed mode-1506 by adding a dependency on streaming to the test metadata.

Current status is that we're getting three failures:

• docbook-001
• sort-079
• unparsed-text-2002

I think the failure in unparsed-text-2002 is unrelated to this issue, and occurs because of recent changes to the W3C web site.
