A pattern is an object that does not gets installed in your system, but
can depend, recommend, suggest, obsolete, conflict with anything else so
it can be used to trigger complex selections. For the pattern to exist,
it has to be in some repo, that is the difference with 1Click, which can
live on its own.

Not true, it depends on the package versions, the vendors, repo
priorities and your system policies.

I haven't implemented patterns in enhancerepo because I don't have a
good idea how to make the user input the data in order to generate the
xml, so it is actually worth it, otherwise you can always write the xml
by hand and use enhancerepo or modifyrepo to add it to the metadata ;-)
