passing parameter for lxslt:script@src

["Fitzharris, Walter M. (LNG-DAY)" <Wa...@lexisnexis.com>]

I would like to create variability where the extension class could
be switched, as in:

   <xsl:param name="fParam" select="'default value'"/>
      
    <lxslt:component prefix="formatter" functions="fullname">     
         <lxslt:script lang="javaclass" src="{$fParam}">
    </lxslt:component>    

=> I guess the above doesn't work  because the script element demands that
the src 
attribute's value be defined at "compile-time".
=>My guess is that the fParam parameter isn't defined until "run-time".  

*	How far off are my guesses above?  
*	How can I create variability like this where the java class for the
extension funcs can be switched?

BTW: hardcoding the src to a class name works fine, and I can print fParam
in a template and it is being set properly in the Transformer...I just can't
use
it in the src attribute.
