Non conformance with XSLT keys

Hi, I have tried to track down a very weird behaviour in one of our XSLTs and tracked it down to something, I believe is a non-conformance of saxon B-9.1.0.6 (also present in 9.1.0.5): Consider the following XSLT stylesheet: <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:tt="http://www.powerware.com/nz/tt"> <xsl:key name="tt:testKey" match="node()" use="('a', 'b')"/> <xsl:key name="tt:testKey" match="node()" use="('a', 'b')"/> <xsl:template match="/"> <xsl:message select="count(key('tt:testKey', 'b'))"/> <xsl:message select="count(key('tt:testKey', 'b'))"/> </xsl:template> </xsl:stylesheet> When run against any input document, I would expect it to print the count of nodes in that document twice. However, it prints the count correctly once and then prints zero for the second message. Has anybody seen this before and even more importantly does anybody have a work-around until this can be fixed? Cheers, Seb

Thanks for getting it down to a simple test case. Looks like a bug that's been there more-or-less for ever: if a named key has more than one xsl:key declaration and a (node, value) pair selected by the second key declaration is the same as a (node, value) pair selected by the first key declaration, then no further values selected by the use expression in the second key declaration for that node are included in the index. It should be an easy fix, which I will do in the morning.
