Getting maintainers help with obsoletes

[Bruno Wolff III]

Twice now I have seen maintainers confused about how to specify release
strings in an obsoletes statement. They like to drop the .fc11 and then
use the version and the rest of the release string from the exact version
they want to obsolete. And this won't work.
Is there some place to more prominently document this?
Is this something rpmlint catches or could be made to catch?
