// EXPERIMENTAL FORM SCRIPTS (Updated 2010-12-02)

// Rewrite of validateForm in jQuery compliant format. Works cross-browser.
// IMPORTANT: The validate mode 'cc' -REQUIRES- jQuery/cc.js to work. Otherwise, it will not.
// IMPORTANT: Conforms to HTML 5 standards. All custom attributes are prefixed with 'DATA-'.
// TODO: wholesalerActiveDates and notZeroActive modes (May not do these at all)
//
// Optional Args:
// @context: Validate fields that meet this context only. Defaults to the calling form tag. Used to validate specific sections of the form only.
