Manage the versions of the various XML libraries in order to prevent class loading issues
When upgrading to last Jena and last CXF, the XML dependencies have been improved.
When these libraries are badly loaded and/or when inconsistencies appear in there version, a lots of bug in Web services (most of the time class loading issues) are introduced.
We have to keep the version of such libraries in the parent POM of helpers and services (the last common parent to components, webservices and portlets).
Here are the version: xml-apis:xml-apis:1.3.04 xml-resolver:xml-resolver:1.2 xerces:xercesImpl:2.9.0 xalan:xalan:2.7.1
