They're not parsed by yum. They're parsed by the web application
handing out the list of mirrors. The resulting file is a list of
mirrors which yum knows how to deal with.

The application could be perl driven, php driven etc. All you're doing
is setting some variables in a web based application, and yum walks
away with the resulting data.
the variable 'repo' is set to 'core-$releasever', where $releasever is
the standard yum variable defined in the config, which is pulled from
a package; usually redhat-release, centos-release, fedora-release,
etc.
