I'm sorry, I mixed up "parse-able" and "valid". I'm suggesting a CSS
Validator profile that only reports parsing errors, but does not
validate against a certain CSS revision. Secondly, I'm suggesting an
additional switch to validate against a certain CSS profile, and copy
extension properties verbatim to the output, giving (at most) a warning
on it, but no error.

This would enhance its usability during private experimental stages.

Regards, Christian.
