JQuery :: Simulate A Validation Group With Validation Plugin?

I have a formdivided into 2 fieldsets (see the image) : MASTER and DETAIL. When I press Add in the DETAIL fieldset a new item is added to an array where I store temporarly the data entered trough the DETAIL inputs and finally when I press save I send both the MASTER and DETAIL (the temporary array shown in the html table) data to the server. As you may have already noticed, I need to validate both MASTER an DETAIL, but I don't want the Save button to fire the DETAIL validation or the Add link to fire the MASTER validation. I've been googling for a while and though I couldn't find exactly what I've been looking for, I found that it's possible to add/remove a class (e.g, required, number); that gave me some ideas on how to simulate validation groups and here's the code:

<script>
$
(
document

[Code]...

Although this code allow me to stop the MASTER validation from firing when I press Add( and DETAIL validation when I click Save), I still can't manage to insert a new DETAIL if only if all of the inputs in the DETAIL fieldset are valid and, what's more I don't want the Add link to cause a form submission.
