* This type defines a container for the response to a

* request is GetFeatureWithLock, the lockId attribute
* must be populated. The lockId attribute can otherwise
* be safely ignored.

* <xsd:attribute name="lockId" type="xsd:string" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* The value of the lockId attribute is an identifier
* that a Web Feature Service generates when responding
* to a GetFeatureWithLock request. A client application
* can use this value in subsequent operations (such as a
* Transaction request) to reference the set of locked
* features.
