Well if you have to you can create a variable describing the new structure 
and then use msxsl:nodeset() function to turn that variable into a nodeset 
and then proceed from there.
You'll need to do this as it's likely that the variable will be a result 
tree fragment (RTF) that can't be processed further.
Alternatively you can do two transforms or switch to a version 2.0 processor 
such as Saxon. Version 2.0 doesn't use RTFs.
Or you could select on *[@scan-code] which then picks any element with a 
scan-code attribute. You can match key and key-sequence elements in 
different templates.
