Gives the following with bcfg2-repo-validate:

When renamed to Packages/sources.xml the error changes to:

The documentation for the 1.2 series release is at ​http://docs.bcfg2.org/dev. The behavior of the Packages plugin has changed in this version as noted at http://trac.mcs.anl.gov/projects/bcfg2/milestone/Bcfg2%201.2.0%20Release. You need to convert your old Packages/config.xml using browser:tools/packages-convert.py.
