Just an FYI because many, many packages use xerces-j2...
I intend to update xerces-j2 from 2.7 to 2.9 (in Rawhide only) once
the package review for xml-stylebook is completed.
Eclipse already expects version 2.9.0 (the OSGi manifest is currently
lying to it) so I don't anticipate any problems in that area.
Hopefully most other packages will be equally unaffected.
