 *              A GetDiff element contains one or more DifferenceQuery elements
 *              that describe a difference query operation on one feature type.  In
 *              response to a GetDiff request, a Versioning Web Feature Service
 *              must be able to generate a Transaction command that can be used
 *              to alter features at fromFeatureVersion and alter them into features
 *              at toFeatureVersion

 *                       The outputFormat attribute is used to specify the output
 *                       format that the Versioning Web Feature Service should generate in
 *                       response to a GetDiff element.

 *                       indicates that the output is an XML document that
 *                       conforms to the WFS 1.1.0 Transaction definition.
 *                       For the purposes of experimentation, vendor extension,
 *                       or even extensions that serve a specific community of
 *                       interest, other acceptable output format values may be
 *                       used to specify other formats as long as those values
 *                       are advertised in the capabilities document.
