jquery locale-aware number validation

Question

I'd like to know if there is any locale-aware way to validate inputs using jquery validation plugin.

In particular, I'm trying to validate a decimal number, but neither max, min, or number methods works as one would expect.

I wrote some small custom validation methods, but I feel like this should/could be delivered right out-of-the-box with jquery.

If there isn't any automatic way to do this validation,do anyone know why is that? Only a matter of implementation priorities (of the jQuery implementation team, I mean)?
