naming forever pre-release versions or svn versions

[Sérgio Basto]

Hi, 
reading
http://fedoraproject.org/wiki/Packaging:NamingGuidelines#Pre-Release_package...

I wonder if we can have or kind of naming for Example (kismet
pre-release svn checkout)

instead kismet-0-0.3.20040204svn to kismet-0-0.3millions.20140204svn  
we could have kismet-0.20040204svn-1 to kismet-0.20140204svn-1
i.e it would be: kismet-0.%{date}svn-release ?

Thanks,
