/**
 * Binding object for the type http://www.opengis.net/wfs:BaseRequestType.

 * <p>
 *        <pre>
 *         <code>
 *  &lt;xsd:complexType abstract="true" name="BaseRequestType"&gt;
 *      &lt;xsd:annotation&gt;
 *          &lt;xsd:documentation&gt;
 *              XML encoded WFS operation request base, for all operations
 *              except GetCapabilities.
 *           &lt;/xsd:documentation&gt;
 *      &lt;/xsd:annotation&gt;
 *      &lt;xsd:attribute default="WFS" name="service" type="ows:ServiceType" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *                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.
 *             &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *      &lt;xsd:attribute default="1.1.0" name="version" type="xsd:string" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *                 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.
 *             &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *      &lt;xsd:attribute name="handle" type="xsd:string" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *                 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).
 *              &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *  &lt;/xsd:complexType&gt;
