Well, look at the definition of XMLOutput (that sole parameter of all 
doTag methods). This is basically a SAX DocumentHandler and it is free 
to your tag to invoke its body with a different XMLOutput (you have to 
invoke it with something!).

You should not try to interfere with the parsing itself: actually a 
script, can, in principle, run several times and only be parsed once. 
Moreover, interfering with the parsing itself would mean the following 
very sad fact: you would not be able to use any of the jelly facilities 
in there, like jexl-expressions, <core:forEach> and this kind of thing: 
they are run by the tags themselves and only the output should interest
