But got the following compiling errors:

Saxon 9.1.0.7J from Saxonica
Java version 1.5.0_06
Error at xsl:template on line 18 column 46 of renameNamespacesKay.xsl:
XPST0081: XSLT Pattern syntax error at char 13 on line 18 in {attribute(*, xs:QName)}:

Failed to compile stylesheet. 2 errors detected.
XSLT run finished

How can I complete the code successfully?
