Project: Xerces2-J
Issue Type: Bug
Affects Versions: 2.11.0, 2.10.0, 2.9.1, 2.9.0, 2.8.1, 2.8.0, 2.7.1, 2.7.0

Upon importing files from wikipedia using mwdumper the script fails in several
files. This happens in multiple dumps (I tried the dumps of May and January). A
file that you can try and it is about ~200 mb is:
enwiki-20130503-pages-meta-history1.xml-p000006887p000009316.7z found in
http://dumps.wikimedia.org/enwiki/20130503/
In mwdumper version using xerces 2.7.1 the error is the following:
