/**
 * @file woden_desc.h
 * @brief Axis2 Description Interface
 * This class provides the implementation for a Description component from 
 * the WSDL Component Model, as described in the WSDL 2.0 specification.  
 * <p>
 * Note: this class is different to the other WSDL implementation classes, 
 * which all implement two interfaces; a component model interface and the 
 * interface for the corresponding WSDL element. Different implementations
 * are used for the Description component and for the &lt;wsdl:description&gt; 
 * element because the latter exposes the composite structure of imported and 
 * included WSDL documents, while the Description component 'flattens' this
 * structure into an abstract view of the WSDL. A separate implementation
 * class, <code>Descriptioni Element</code>, exists to represent
 * the &lt;wsdl:description&gt; element.
