Is the purpose to group similar packages together for ease of
presentation, or to actually create some relationship between packages? 
For grouping, Red Carpet just maps various RPM "Groups" (and the dpkg
equivalent, I don't remember what it is exactly now) into friendlier
categories for end-user presentation.

The upcoming libredcarpet/rcd 2.0 has the concept of "package sets"
which have a special kind of dependency relationship between them.  We
added a "child" dependency relationship, which is similar to
requires/depends except that when the package set is removed, the
children are as well.

I'm not sure how/if we can somehow wedge this into the common metadata
format.  Adding a new type for it that other programs don't understand
would probably help.
