This doesn't begin to cover a lot of what XML is used for. It does
cover document-like uses, but not the data-serialization uses.
In the latter, folks want their application objects, not objects
that accurately reflect the source document. They need something
more like marshalling/unmarshalling code, going straight to the
app-meaningful objects.

Even for some documentation-like uses, a DOM is the wrong answer.
Our search engine needs to extract text and store it in the indexes.
Analyzing the documents in a stream (SAX) means handling bigger
documents, using less memory, et cetera.
