But then the XML output is not what I would call readable anymore which violates goal number 6
in the XSL draft:

"XML documents should be human-legible and reasonably clear."

Once a document has been read into memory it may lose all of the original structure (maybe
transformed is not the right word here).  You no longer preserve the prefix names that the
original author of the content (or even DTD) had intended.  What you write out to XML may no
longer conform to any DTD.

What I mean is simply, once you read in a document, you process it and then you are done with
it.  I suppose "throwing it away" was a little inaccurate.

Sorry for the misunderstanding here,
