Hi
Doing some validations, I get with some bad usage of [valid_string] rule, because the way to use is different to the rest of the rules. At the beginning I though was a bug, doing research I found the answer.

I think will be great if we can have small examples for this kind of things.
Thanks.
More examples is on our (very long) todo list.
You can help by forking the docs repository, make suggested changes, and send a pull request. Any help will be greatly appreciated.
