Therein lies the nub of the issue, the words "the same". Lexical approach: Leaves lots of the document "the same" but it is very difficult to get the processing right in the face of all the things that are hidden beneath the term "DTD valid XML". foo1.xml is an example of these gotchas. Parser based approach: A lot easier to get the processing right but fiendishly difficult to leave unprocessed parts of the document "the same" in the face of all the things hidden beneath the term "DTD valid XML". The output of a SAX or XSLT transform of foo1 is an example of the problem. Grove/Infoset approach: Possible to get the processing right and leave the document "the same". Serious complexity jump both in terms of the underlying abstractions to grasp and the coding required. My oft-repeated thesis is that I am loath to concede that the complexity of the grove/infoset approach is unavoidable. I am championing the complete separation of DTD and instance as a first step towards exploring an alternative, layered approach to this sort of processing which makes a parsing based paradigm workable whilst leaving the unaffected parts of a document "the same" en route to further processing stages.

Same here.
