These track the various features that the binary package is using.  If
we didn't track these, an older version of rpm might interpret the
information in the package incorrectly.

when you invoke rpm, it internally satisfies (provides) these
dependencies.  An easy way to test is to look at the version number in
the rpmlib requirement and see if the version of rpm that you have is
greater than or equal to that version.

The nitty-gritty is in rpm/lib/rpmlibprov.c
