/*
		Apply these class names to form elements:

		* required (not blank)
		* validate-number (a valid number)
		* validate-digits (digits only, spaces allowed.)
		* validate-alpha (letters only)
		* validate-alphanum (only letters and numbers)
		* validate-date (a valid date value)
		* validate-email (a valid email address)
		* validate-url (a valid URL)
		* validate-date-au (a date formatted as; dd/mm/yyyy)
		* validate-currency-dollar (a valid dollar value)
		* validate-one-required (At least one checkbox/radio element must be selected in a group)
		* validate-not-first (Selects only, must choose an option other than the first)
		* validate-not-empty (Selects only, must choose an option with a value that is not empty)
		* validate-regex (requires the element to have a 'regex=' attribute applied)

		Also, you can specify this attribute for text, passwird and textarea elements:
		* minlength="x" (where x is the minimum number of characters)
