comps.xml has doctype with invalid dtd reference

[bmbouter]

Consider the latest Fedora compose which uses createrepo_c. Look at the comps.xml file. you'll see something like this:

<!DOCTYPE comps PUBLIC "-//Red Hat, Inc.//DTD Comps info//EN" "comps.dtd">

It would be more correct to use this one: https://pagure.io/fedora-comps/blob/master/f/comps.dtd

I've also written some about other options here: https://pulp.plan.io/issues/1786#note-4

This problem seems to be still present even on current comps.xml. However createrepo_c is not generating these group files. It is only able to add it to repodata, either when creating them with createrepo_c -g /path/to/comps.xml . or later with modifyrepo_c /path/to/comps.xml ..

Repodata xml files created by createrepo_c are missing dtd references altogether, but that is probably a separate issue.
