RE: Debugging XSL with XML Spy 5

If this is so, then they have disguised it very effectively. The error messages are completely different from Saxon's, and it has completely different bugs - ten minutes' experimenting showed that it doesn't allow forwards references to global variables, and it displays number(0.00005) as "0". It also signals some errors that Saxon recovers from. (But I did find one bug in common - they don't required xsl:param to be the first instruction in a template, which is a bug that was in Saxon 6.5.2 and earlier releases). If their product was derived from Saxon, then under the Mozilla Public License they would be obliged to make their source code freely available.
