/**
 * @file woden_ext_element.h
 * @brief Axis2 Extension Element Interface
 *          This interface represents WSDL 2.0 extension elements. That is, 
 *          any XML element information items that appear as [children] of a 
 *          WSDL 2.0 element and are not in  the WSDL 2.0 namespace 
 *          (http://www.w3.org/2006/01/wsdl).
 *          <p>
 *          Based on a similar interface from WSDL4J element extensibility.
 *
 *          TODO change this URL if the WSDL 2.0 namespace changes before spec 
 *          is finalized.
