Have a look at the 3rd party repos, they all have disttags by now
using "." and "_". So technically these are known to work and also
there is some consensus on using something like

      <releqasetag> := <buildid><sep><disttag>[<sep><repotag>]

buildid are either single integers, or decimal seperated decimals
(like in forks or CVS tags), disttag is "fc2" or "rhfc2" (please use
lower caps, FORTRAN is out :), and the last part is something a vendor
(RH) should not need to attach, so don't consider it.

(note: the releasetag definition above dsoe not consider the special
case or pre/alpha etc. releases for simplicity's sake)
