 *          <xsd:documentation>
 *              This type defines the LockFeature operation.  The LockFeature
 *              element contains one or more Lock elements that define which
 *              features of a particular type should be locked.  A lock
 *              identifier (lockId) is returned to the client application which
 *              can be used by subsequent operations to reference the locked
 *              features.
 *           </xsd:documentation>

 *                      <xsd:annotation>
 *                          <xsd:documentation>
 *                          The lock element is used to indicate which feature
 *                          instances of particular type are to be locked.
 *                       </xsd:documentation>

 *                  <xsd:annotation>
 *                      <xsd:documentation>
 *                       The expiry attribute is used to set the length
 *                       of time (expressed in minutes) that features will
 *                       remain locked as a result of a LockFeature
 *                       request.  After the expiry period elapses, the
 *                       locked resources must be released.  If the
 *                       expiry attribute is not set, then the default
 *                       value of 5 minutes will be enforced.
 *                    </xsd:documentation>
 *                  </xsd:annotation>

 *                  <xsd:annotation>
 *                      <xsd:documentation>
 *                       The lockAction attribute is used to indicate what
 *                       a Web Feature Service should do when it encounters
 *                       a feature instance that has already been locked by
 *                       another client application.
 *
 *                       Valid values are ALL or SOME.
 *
 *                       ALL means that the Web Feature Service must acquire
 *                       locks on all the requested feature instances.  If it
 *                       cannot acquire those locks then the request should
 *                       fail.  In this instance, all locks acquired by the
 *                       operation should be released.
 *
 *                       SOME means that the Web Feature Service should lock
 *                       as many of the requested features as it can.
