See: http://forum.kohanaphp.com/comments.php?DiscussionID=2192.
Note that the methods with an <em>_invalid</em> suffix contain flawed regexes and should be
completely discarded. I left them in here for educational purposes, and to remind myself
to think harder and test more thoroughly. It can\'t be that I only found out so late in
the game. For the regex explanation have a look at the forum topic mentioned earlier.';
