Description

The specification of fn:transform() states:

When source-node is supplied then the global-context-item (the context item for evaluating global variables) is the root of the tree containing the supplied node.

Test case fn-transform-82b in QT3 is failing; it appears that the global context item is set to the supplied value of source-node, not to the root of the containing tree.

Test fn-transform-82e is failing for the same reason (though it's not clear we should be running this test since it requires an XSLT 2.0 processor).

For transform-82e I think the results we produce should be allowed.

The test requests xslt-version:2.0, but the spec says:

If a processor that implements the requested XSLT version is available, then it is used.
Otherwise, if a processor that implements a version later than the requested version is available, then it is used.

So we're allowed to use an XSLT 3.0 processor; and if we do, then the global-context-item option will not be ignored as the test appears to expect.

However, if we make this change to the test, then Saxon/J 10.2 fails it.
