The rules for what is valid are set out at

  http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version

python-debian has debian.debian_support.BaseVersion that could be of
use. That defines

      re_valid_version = re.compile(
            r"^((?P<epoch>\d+):)?"
             "(?P<upstream_version>[A-Za-z0-9.+:~-]+?)"
             "(-(?P<debian_revision>[A-Za-z0-9+.~]+))?$")

Rules for how version numbers are allowed to evolved are a different
matter.
