Suppose we have two stylesheets: main.xsl <xsl:stylesheet version="2.0" xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:x="http://www.example.org/alias" xmlns:y="http://www.example.org/My/Transform/Language"> <xsl:import href="import.xsl" /> <xsl:namespace-alias stylesheet-prefix="x" result-prefix="y"/> <xsl:template match="/"> <x:transform /> </xsl:template> </xsl:stylesheet> import.xsl <xsl:stylesheet version="2.0" xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:x="http://www.example.org/alias" xmlns:y="http://www.example.org/My/Transform/Language"> <xsl:namespace-alias stylesheet-prefix="x" result-prefix="#default"/> </xsl:stylesheet> Is "http://www.w3.org/1999/XSL/Transform" (ordinarily an excluded namespace) considered as a target namespace URI, even though the xsl:namespace-alias is overridden by a higher priority xsl:namespace-alias for the same literal namespace URI? i.e. is the correct result: <y:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:y="http://www.example.org/My/Transform/Language"/> or <y:transform xmlns:y="http://www.example.org/My/Transform/Language"/> ? I would presume that the latter is correct, because "http://www.w3.org/1999/XSL/Transform" is not going to be used in the result tree as a substitute for a literal namespace URI due to the higher precedence xsl:namespace-alias declaration. 35849 1 mike 2010-05-27 15:04:07 +0000 I guess that the statement "If a literal namespace URI is declared to be an alias for multiple different target namespace URIs, then the declaration with the highest import precedence is used." could be expanded with "..., and the other declarations have no effect." Would this remove any remaining doubts? 35850 2 tim 2010-05-27 15:10:13 +0000 Yes. Just to be clear, do you agree that <y:transform xmlns:y="http://www.example.org/My/Transform/Language"/> is the correct answer? 35852 3 mike 2010-05-27 15:48:52 +0000 I've added this as test case nspc-n144. The answer I get from Saxon is <?xml version="1.0" encoding="UTF-8"?> <y:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:y="http://www.example.org/My/Transform/Language"/> which I believe is incorrect, for the reasons described. 35853 4 tim 2010-05-27 16:13:13 +0000 Thanks. We believe we have found a number of errors in the test suite. Where should we report them? 35854 5 mike 2010-05-27 16:18:21 +0000 Please report errors in the XSLT testsuite in the W3C "member-private" Bugzilla database, http://www.w3.org/Member/bugzilla/ - product "XSLT 2.0 CR Test Collection". 36902 6 mike 2010-07-15 09:56:09 +0000 Closing as WORKSFORME - the spec is correct, the test case was wrong.
