Saxon

The following code fails to compile the attached XSLT. It did compile with earlier versions of HEC (notably 1.2.1 albeit with some C++ code differences)

#include <string>

using namespace std;

#include <Saxon.C.API/SaxonProcessor.h>
#include <Saxon.C.API/XdmValue.h>
#include <Saxon.C.API/XdmItem.h>
#include <Saxon.C.API/XdmNode.h>

int main(int argc, char **argv)
{
	SaxonProcessor *saxon = new SaxonProcessor(true);
	Xslt30Processor *trans = saxon->newXslt30Processor();
	XsltExecutable *exe = trans->compileFromFile(argv[1]);
	if (trans->exceptionOccurred())
	{
		printf("1: %s\n", trans->getErrorMessage());
		return 1;
	}
	XdmNode *node = saxon->parseXmlFromFile(argv[2]);
	if (saxon->exceptionOccurred())
	{
		printf("2: %s\n", saxon->getErrorMessage());
		return 1;
	}
	if (!node)
	{
		printf("3: failed to parse xml\n");
		return 1;
	}
	exe->setGlobalContextItem(node);
	if (exe->exceptionOccurred())
	{
		printf("4: %s\n", exe->getErrorMessage());
		return 1;
	}
	string xform = exe->transformToString();
	if (exe->exceptionOccurred())
	{
		printf("5: %s\n", exe->getErrorMessage());
		return 1;
	}
	printf("%s\n", xform.c_str());
	return 0;
}

The trans->compileFromFile fails with the attached style sheet. Is there an opinion out there whether it should have succeeded (my code wrong or stylesheet wrong perhaps) ?

The exception i get is:
