Not yet, since I don't think anyone's had both installed yet. <g>

Hmmm, not good.  Sounds like we'll have some subtle issues to work around
when porting to libxml2 ;-(

Currently we don't move because very few people have libxml2 right now.
Everyone's got the older 1.8.x series, and if we started requiring
libxml2, we'd keep a lot of people from trying GStreamer.  That said, we
definitely have to look into dealing with the libxml2 case, both in
figuring out which one is being found at configure time and changing the
code to handle the differences in API...

If you have any luck figuring out what changes are needed to get the
libxml2 stuff to output the right stuff, please send us mail or even
patches, we'll get them integrated in CVS ASAP.
