title: How to inject string properties containing < character into Spring beans?
body: <p>I have following bean definition for my DAO - </p>
  
  <pre><code>&lt;bean id="userDao" class="UserDao"&gt;
  &lt;property name="dataSource" ref="dataSource" /&gt;
  &lt;property name="queryPurgeInvalidReferrals" value="delete from reference where date &lt; ?" /&gt;
  &lt;/bean&gt;
  </code></pre>
  
  <p>I am getting the error - 
  The value of attribute "value" associated with an element type "property" must not contain the '&lt;' character.</p>
