One of the Upgrades we will be implementing in eCart is to have the Form Builder engine generating the Checkout pages.
In eCart will be upgrading the Form Builder engine to generate HTML 5 forms using jQuery for validation. So basically the jQuery upgrade will start with eCart 6. eCart 6 will upgrade form builder to use jQuery validation, after that we will be upgrading Data Bridge so that the Data Bridge form builder contains the jQuery validation natively.
