 "group" attributes on html elements which run on the server
 allow each group to be passed to the client with the clientID so it can be accessed by client side javascript

 "manditory" attributes are used for validation of manditory controls
 they are passed to the client in the same way

 i.e. <input type="checked" group="theCheckBox" manditory="checked" />
	the list of options are: NonEmpty, Checked, etc...
