XSLT programs of this type are not *self*-modifying. Rather, they modify
other code that happens to resemble themselves. It is then up to something
outside the XSLT environment to re-execute the modified code.
This is no more a case of self-modification than when a compiler compiles a
modified version of itself: the new compiler must be put into effect by
something outside itself, typically an installation routine.
