title: Jsp custom tag with value of an attribute as another custom tag
body: <p>I am creating some jsp custom tags.Now I have a requirement as follows :</p>
  
  <pre><code>&lt;bb:custom1 id="id1" attr1="&lt;bb:custom2 attr2='attr2val'&gt;&lt;/bb:custom2&gt;"&gt;&lt;/bb:custom1&gt;
  </code></pre>
  
  <p>ie the value for an attribute should be another custom tag which will be resolved by the corresponding tag handler. I could see that this works with all the html tags.But when i tried with my custom tags it does not work.Can some one please tell me how this can be attained.</p>
