Probably not within the extension mechanism. An RPM package cannot, for
example, require kernel features either, even though that is
occasionally an actual requirement of some package. Moreover, declaring
such a dependency wouldn't actually help making the dependency
available, because you cannot just install the dependency, you need to
rebuild the (OS/DBMS) kernel.
