/*	
	The 'target' attribute is not valid XHTML. Best practice is to use the 'rel' attribute 
	to assign the link a relationship. For ex. if you link outside of your domain you could assign
	rel="external". This is semantically proper but adds no functionality. You can later run a javascript
	function to add targetting functionality (ex. open in new window) as the function does below.
	
	NOTE: You normally want to give the user the control to open a link in a new window or tab. This function
			should be used in a limited manner or not at all.
