/**
 * @brief Interface definition for the ValidateResult elements
 *
 * The \<ValidateResult\> is one of the fundamental message types of
 * the XKISS service.  It is used by the Validate service to return a key
 * and the bindings for that key.
 *
 * The schema definition for ValidateResult is as follows :
 *
 * \verbatim
   <!-- ValidateResult -->
   <element name="ValidateResult" type="xkms:ValidateResultType"/>
   <complexType name="ValidateResultType">
      <complexContent>
         <extension base="xkms:ResultType">
            <sequence>
               <element ref="xkms:KeyBinding" minOccurs="0" 
                     maxOccurs="unbounded"/>
            </sequence>
         </extension>
      </complexContent>
   </complexType>
   <!-- /ValidateResult -->
\endverbatim
