Thanks a million for this link.

Got it. I've reversed it. I'm doing it this way, now.
Since I've found little documentation on how to do this, here's a
simplified procedure:
1. Create the patterns.xml file with all the pattern
definitions.
2. Convert to groups/comps using the XSL provided in
meego-os-base/package-groups
3. Create the repos like this (abbreviated):
## Copy RPM packages to a folder, repos/
$ mkdir -p repos/repodata
$ cp -f patterns.xml comps.xml repos/repodata
$ createrepo -g repos/repodata/comps.xml repos/
$ modifyrepo repos/repodata/patterns.xml repos/repodata
4. Sign the file repos/repodata/repomd.xml
Since I had a hard time finding the docs on these XML schemas, here's some
documentation links that I
found:
Relax NG Schemas:
http://gitorious.org/opensuse/libzypp/trees/master/zypp/parser/yum/schema/
Repos Metadata: http://en.opensuse.org/openSUSE:Standards_Rpm_Metadata
Patterns File:
http://en.opensuse.org/openSUSE:Standards_Rpm_Metadata_patterns
And, finally, I've added some stuff to the MeeGo Wiki here:
