replace multiple distinct strings

I'm attempting to write a javascript escape function like template in xsl.  
I wish to escape text to it's URL escaped form (i.e. %xx where x is a hex 
digit).
I've tried two different style sheets that I think should accomplish the 
same thing.  However, I end up with the following error:  
javax.xml.transform.TransformerException: java.lang.RuntimeException: 
Invalid conversion from ?reference? to ?java.lang.String?.
I am using xalan 2.4.1 (cannot use 2.5.1 because of carriage return bug 
23147) xsltc to compile and cache my stylesheets.
Below is listed the stylesheet, the two templates, then followed by sample 
xml for processing and the "replacement" xml.
