Given one has to compare 2 input sources
simultaneously, using SAX gets much trickier. So for
this particular use case, Stax API seems more optimal.

However, it's still not entirely clear as to what
exactly is meant with equality: how strict is it? Is
it logical or physical equality (do different
namespace prefixes matter? Ordering of attributes?
Ignorable white space? Use of CDATA vs. characters

I personally like using Canonical XML for comparisons,
which is geared more towards logical equality. XOM
implements this nicely for what that's worth.
