Question regarding version + svn revision on packaging

[Nelson Marques]

One of the packages I'm submitting for Unknown Horizons support
(python-enet or pyenet) has no real version and it's just svn revision
24 (python bindings for ENet);
What would be the best way to express this in the spec file?

ex: Version: 0.0.0+svn24

Or any other? Opinions most welcome.
