My understanding is that this is a foggy area of the XML spec.  The most 
recent spec says the xml namespace is implicitly declared - previously, 
nothing was said.  Some parsers do not do well with this attribute 
(xmlns:xml).  IE's parser is among them.

This attribute is new in GeoServer 1.7.2.  I've opened an issue there:
http://jira.codehaus.org/browse/GEOS-2606

I'll see if we can come up with a workaround on our end.
