Ah, got it. I thought you were looking for an all-OpenPKG distro  
solution.

Adding a release(N) name space is a perfectly obvious solution
using a getter access method and usual strcmp-like comparison
overloaded into existing rpm dependencies.

The subtly is that there may be multiple N installed with different  
R, and
it may not be clear what "package" needs to be accessed to compare R.

So you also need a compound statement to insure that you have exactly
the package you wish to compare against.

rpm already permits A as a compound as in
	Requires: N.A = E:V-R
A general namespace form for (at least) the important tags like NEVRAO
might look like (I use XXX to designate "package" item and avoid  
confusions)
	Requires: Release(XXX) = "R"
with generalization to the compounds
         Requires:  Name(XXX).Arch(XXX).Release(XXX) = "N A R"

The tricky part is that the elements accessed by the getters need
to be loaded by rpmdsNew() so that thousands of added package
headers don't need to be present in memory.
