As David explains, there's not much point in this.  However, user
extensions might do what you want.  In many cases you can define an
extension that can called at any point in your XSLT.  You can then
pass any nodeset or variable into this function and, in general, it
can create a nodeset or string as output back into the XSLT.  However,
in your case you wouldn't necessarily have to return anything...
