 * @brief Interface definition for the ValidateRequest elements
 *
 * The \<ValidateRequest\> is one of the fundamental message types of
 * the XKISS service.  It is used by the Validate service to find a key
 * and return a set of key bindings for that key.
 *
 * The schema definition for ValidateRequest is as follows :
 *
 * \verbatim
   <!-- ValidateRequest -->
   <element name="ValidateRequest" type="xkms:ValidateRequestType"/>
   <complexType name="ValidateRequestType">
      <complexContent>
         <extension base="xkms:RequestAbstractType">
            <sequence>
               <element ref="xkms:QueryKeyBinding"/>
            </sequence>
         </extension>
      </complexContent>
   </complexType>
   <!-- /ValidateRequest -->
