CD>   <!-- Do what you want with the bean -->
CD>  <logic:present name="chapter">

CD> </logic:present>

CD> Advantages of this approach :

CD>    * No need to modify existing logic tags
CD>    * No template stuff in struts core library : Struts and templates
CD>      still well separated
CD>    * Imported bean value can be used in any others tags accepting a bean

CD> This proposed solution already exist in Components / Extended Templates.
