A better place is:

  XSL-List info and archive:  http://www.mulberrytech.com/xsl/xsl-list

Such a criterion is available using W3C XSLT, not IE5 XSL ... with W3C XSLT 
you can specify a sort key based on a function.

Oh.  I'm not really sure what you are asking for, then.

Have you examined using general entities (but may not work in IE5) to 
parameterize the encoding of attributes and sub-elements?

Same answer from me ... such parameterization as I *think* you've described 
isn't possible in XSLT.  But, I think if you were to parameterize the 
*stylesheet markup* instead of trying to parameterize *stylesheet 
behaviour*, you will get what you are looking for.

Also, I expect you want to do "//element[..." to choose from all elements 
with the given predicate (which is not quite what you are asking for).

I hope this helps.
