Is there a way to create a multiline text graphic and place on the map in a workflow

With the HTML viewer we want to create a workflow that places a multiline text graphic based on several attributes of a feature such as:

 

100 W

 

ABC

 

10k OHM

 

All in one text graphic.  Is this possible?  We've tried various line break characters such a \n, <br\>, <br>, and even &lt;br/&gt; but it all just gets written exactly as is.  How can we make this happen?
