The GNU JAXP version of DOMImplementationLS that IKVM now includes
doesn't have this method (in fact, it looks nothing like the
DOMImplementationLS interface on w3c page). I don't know why this is or
what this means.

Note that it doesn't matter that Xerces includes a correct version of
the interface, since IKVM already has the interface in its core classes,
you cannot replace it (well, actually, you can but you'd have to play
some class loader games (i.e. write a class loader that violates the
rules)).
