title: WBR Alternative in XHTML
body: <p>I've been using  tags in the thead cells for my tables, so I can control where browsers break long words.  This works great, but its not XHTML compliant.  What is the best alternative to using the wbr tag, that is valid XHTML?  Example:</p>
  
  <pre><code>&lt;table&gt;
    &lt;thead&gt;
      &lt;tr&gt;&lt;th&gt;ThisIsAReally&lt;wbr /&gt;LongWord&lt;th&gt;&lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
      &lt;tr&gt;&lt;td&gt;...&lt;/td&gt;&lt;/tr&gt;
      &lt;tr&gt;&lt;td&gt;...&lt;/td&gt;&lt;/tr&gt;
      &lt;tr&gt;&lt;td&gt;...&lt;/td&gt;&lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
