Transformers and namespace issues

[Christopher Hull <ch...@mediagate.com>]

Ok, this brings me to what appears to be my last problem in my effort to 
upgrade to Xalan 2.  I may be doing something funny with name spaces
in my XSL, and now all of a sudden it appears as though my XSL 
extensions can no longer be found by Xalan's new transformers.

Here is the header from a stylesheet that establishes a 
"StringFunctions" namespace and includes these functions.
  -----
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	version="1.0"
xmlns:StringFunctions="C:/qs/tomcat/webapps/qsdocs/common/en_US/html/StringFunctions.xsl"
	extension-element-prefixes="StringFunctions">
	
  -----
Later in the XSL a function is called like this...

</xsl:attribute><xsl:value-of 
select="StringFunctions:first15Chars(string($textLabel))"/>
  -----

When a transformer runs this, it throws an exception saying that it 
can't find extension call first15Chars (I'll try to get the exact 
exception if this is not enough information).

What am I doing wrong?  What has changed with this regard from Xalan 
1.x?  Do I need to tell transformers to be namespace aware somehow?

Thanks again;
-Chris
