Adding line breaks in Title attribute

This html is an example of what I am looking for, I took this from the
mock up I developed and works on IE6.0. The xml I am using Is below
also. The problem is that I can not seem to get the xsl to put the
line break between the last name and the order disposition as it works
in the mockup.

<button id="shoppingCart" title="Jenny Peterocceli &#10; Validated"
class="tabText">Customer Account<br/>Jenny Peteroccelli</button>

<ORDER num="3">

         <first_name>Meaghan</first_name>
