I'm highly doubtful that there's any real need for different kinds of
repository-provided sets. We especially don't want sets to be code...

No, that's something that's determined by how the set's used, not by
what's in the set. There's no such thing as a "one-of" set; a set is
just a list of package dep specs.

from scratch than it does to get the results out of an XML parser.
