//			is cleared
//		lqunselect, lqclear
//			Example: <INPUT TYPE="CheckBox" NAME="Q624" unselect VALUE="31">
//			Description: makes check box initially unselected when page is loaded.
//		lqanswerconnect:
//			Example: 
//				<INPUT TYPE="CheckBox" NAME="Q536" VALUE="13">
//				<TEXTAREA NAME="Q536:O" lqanswerconnect="13"></TEXTAREA>
//			Description: when text is entered into textbox - the answer alternative is selected
