All a subpackage is is a separate binary package built from the same 
source/spec at the same time. So for instance there's zlib and 
zlib-devel, both built from the zlib src.rpm. The -devel package 
contains various things that not all users of zlib will need, so it's 
broken out into a subpackage so that those bits don't need to be 
installed unless you actually need them. As far as RPM itself is 
concerned, once the subpackages are built, they're entirely separate 
packages with no relationship between them (though it's usually the case 
that the packager will specify in the spec file that one depends on the 
other, e.g. you can only install zlib-devel if you have zlib installed).
