[ER2] Fuse MRRC validation errors

Hi,

attaching the validator output for the CR1 repository. I've added multiple remote repositores to search artifacts in, as suggested by Darren on mailing list:

-rr http://repository.jboss.org/nexus/content/groups/fs-public/ -rr http://repository.jboss.org/nexus/content/groups/ea/ -rr http://maven.repository.redhat.com/techpreview/all/

I did also silence xml validation and suspicious file exceptions for *maven-metadata.xml.
