A XSLT processor may not use DOM internally but rather an own tree model 
which is better suited to implement optimizations.
(like Saxon and jd.xslt do). If you pass a DOM tree, then the processor 
could choose to rebuild the tree in its internal model.

So if you have the choice to pass the input as DOM tree or as SAX events, 
then choose SAX, therefore making less assumptions about the processors 
inner workings.
But if you already have constructed the DOM, then pass the DOM.
