It's not necessary to require that to make NVR strings parseable, since 
the release is unambiguously delimited by the final '-' in the string.

Nevertheless, the release field certainly should begin with a digit, 
since it would be confusing otherwise.

Technically valid, but falling under the "you should try to avoid this" 
clause. Changing the '-' to a '_' is probably the best option.
