At least that's true for what came from MS so far. I don't think that that's true in general. Most of the Java-based XML parsers I've tried seem to be able to handle Jon Bosak's XML Old Testament (nearly 4MB) just fine, if somewhat slowly -- I used ot.xml for routine testing and profiling while developing AElfred, and AElfred barely kicked up a sweat. The problem comes if the parser tries to build a tree rather than simply reporting an event stream. Depending on the implementation, document trees tend to be very large. With a naive tree implementation, a 10MB document might use 100MB or more of virtual memory for the document tree -- that'll bring most current desktop systems to a screeching halt.
