Re: "Version less than 0.0" in OVAL definitions

Hello,
In theory, from version number numbering point of view only, yes less than
0.0 is valid. But in practice, as they are used in Debian OVAL definitions,
I don't think they are. I think these state values might be incorrect,
probably unintentionally. And there are many, thousands, of these less than
0.0 versions, I don't think they are actually intended to test for pre
version 0 releases.
For example, who could be using a pre version 0 release of glibc?
