Well, there are other systems around (e.g. ConfigObj) which will allow
you to validate against a schema, but it's not part of the core so
logging can't rely on it.

I'm not sure how much interest there'd be in adding this kind of
validation to ConfigParser, but you could always try working up a patch
and assigning it to whoever maintains ConfigParser, or contacting that
person beforehand to see if it's worth it, or posting on c.lpy with the
same objective.
