Subject RE: [C2][SAXON] NodeIterator/NodeList in SAXON extensions.
Date Wed, 14 Mar 2001 21:00:30 GMT
Saxon will now call the version of getParameterSource() that takes a
NodeList parameter. It won't call the one that takes a NodeIterator, 'cos I
don't support that yet (and it's not in XSLT 1.1 either), and it doesn't
work if both methods are present, because Saxon doesn't yet support
polymorphic methods.

New version should be out in the next few days; I've got a bit of a backlog
of bug fixes to apply first, then some regression testing.
