[jQuery] [Validate] list of metadata options?

[jQuery] [Validate] list of metadata options?


I may be missing something obvious. The docs for Validation (http://
docs.jquery.com/Plugins/Validation) are very clear on the JavaScript
API. But I'm trying to find documentation on what is supported in
metadata. The example uses:
<input id="cemail" name="email" size="25" class="required email" />
Which tells me that this field is required and must be a valid email
address, but nowhere do I see a list of what kind of stuff can I use
in the class field. Can I do required url, required number, etc? Is
this documented somewhere and I'm just missing it?
