              The service attribute is included to support service 
              endpoints that implement more than one OGC service.
              For example, a single CGI that implements WMS, WFS
              and WCS services. 
              The endpoint can inspect the value of this attribute 
              to figure out which service should process the request.
              The value WFS indicates that a web feature service should
              process the request.
              This parameter is somewhat redundant in the XML encoding
              since the request namespace can be used to determine
              which service should process any give request.  For example,
              wfs:GetCapabilities and easily be distinguished from
              wcs:GetCapabilities using the namespaces.

               The version attribute is used to indicate the version of the
               WFS specification that a request conforms to.  All requests in
               this schema conform to V1.1 of the WFS specification.
               For WFS implementations that support more than one version of
               a WFS sepcification ... if the version attribute is not 
               specified then the service should assume that the request
               conforms to greatest available specification version.

               The handle attribute allows a client application
               to assign a client-generated request identifier
               to a WFS request.  The handle is included to
               facilitate error reporting.  A WFS may report the
               handle in an exception report to identify the
               offending request or action.  If the handle is not
               present, then the WFS may employ other means to
               localize the error (e.g. line numbers).

            The Property element is used to specify one or more
            properties of a feature whose values are to be retrieved
            by a Web Feature Service.

            While a Web Feature Service should endeavour to satisfy
            the exact request specified, in some instance this may
            not be possible.  Specifically, a Web Feature Service
            must generate a valid GML3 response to a Query operation.
            The schema used to generate the output may include
            properties that are mandatory.  In order that the output
            validates, these mandatory properties must be specified
            in the request.  If they are not, a Web Feature Service
            may add them automatically to the Query before processing
            it.  Thus a client application should, in general, be
            prepared to receive more properties than it requested.

            Of course, using the DescribeFeatureType request, a client
            application can determine which properties are mandatory
            and request them in the first place.
