I was about to post something along the same line and I actually mailed 
perl-XML-Xerces upstream yesterday. There is no perl-XML-Xerces version 
that can be compiled against xerces-c-2.8.0 and there won't be in the 
near future.

Even if the soname bump is a no-no for EPEL, there's no way to update 
the perl package in Fedora either, so I'd be very grateful if the 
xerces-c update never hits Fedora stable. I don't really care about 
devel, but the perl package will likely remain broken there until 
xerces-3.0.
