title: Put linebreak/newline in tooltip
body: <p>I'd like to put a linebreak in a tooltip so that it displays like:</p>
  
  <blockquote>
    <p>Nom: value1<br>
    Quality: value2</p>
  </blockquote>
  
  <p>I tried:</p>
  
  <p><a href="https://stackoverflow.com/questions/11302236/concatenating-strings-in-el/11302880#11302880">1</a>.</p>
  
  <pre><code>&lt;h:outputText title="Nom: #{cntc.value1}&amp;lt;br/&amp;gt;Quality: #{cntc.value1}" /&gt;
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/7386133/concatenating-strings-within-el-expression-defined-in-an-attribute-of-a-facelets">2</a>.</p>
  
  <pre><code>&lt;h:outputText title="Nom: #{ (''.concat(cntc.value1).concat('&amp;lt;br/&amp;gt;')concat('Quality: ').concat(cntc.value2)}" /&gt;
  </code></pre>
  
  <p>None of them worked for me. It seems that the <code>&lt;br/&gt;</code> isn't being interpreted.</p>
  
  <p>How can I achieve this?</p>
