/**
 * 
 * A AjaxRender that creates a XML structure from
 * a given String.
 * 
 * By default, it gets from the action's output a String identified by the key "value" and
 * generates a XML structure with a sigle tag named "value", with the body content as the value
 * from the output, but this behavior can be changed at the constructor.
 *   
 * 
 * Example of a generated XML:
 * 

 * <value>valueFromOutput</value>
