title: How to use <spring:message> inside an attribute of <form:input>?
body: <p>I have JSP code like:</p>
  
  <pre><code>&lt;div class="formRow"&gt;
      &lt;form:input id="email_email" name="email_email" title="XXXXX"/&gt;" path="email" cssClass="input required email" /&gt;
      &lt;form:errors path="email" cssClass="error" /&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to set the <code>title</code> attribute with some tooltip text, supporting i18n.  How would I do this?</p>
  
  <p>I am looking to do something like this:</p>
  
  <pre><code>&lt;div class="formRow"&gt;
      &lt;form:input id="email_email" name="email_email" title="&lt;spring:message code="tooltip.text" /&gt;"/&gt;" path="email" cssClass="input required email" /&gt;
      &lt;form:errors path="email" cssClass="error" /&gt;
  &lt;/div&gt;
  </code></pre>
