[jQuery] validation plugin's date method doesn't like mm-dd-yyyy formatted dates


I'm using this validation plugin http://bassistance.de/jquery-plugins/jquery-plugin-validation/
and it is great.
However, it rejects dates like 07-14-2009 as invalid. Is there some
way to add a list of valid formats?
If not, should I write my own method to match that particlar format?
