 *              The DescribeFeatureType operation allows a client application
 *              to request that a Web Feature Service describe one or more
 *              feature types.   A Web Feature Service must be able to generate
 *              feature descriptions as valid GML3 application schemas.
 *
 *              The schemas generated by the DescribeFeatureType operation can
 *              be used by a client application to validate the output.
 *
 *              Feature instances within the WFS interface must be specified
 *              using GML3.  The schema of feature instances specified within
 *              the WFS interface must validate against the feature schemas
 *              generated by the DescribeFeatureType request.
 *           &lt;/xsd:documentation&gt;
 *      &lt;/xsd:annotation&gt;
 *      &lt;xsd:complexContent&gt;
 *          &lt;xsd:extension base="wfs:BaseRequestType"&gt;
 *              &lt;xsd:sequence&gt;
 *                  &lt;xsd:element maxOccurs="unbounded" minOccurs="0"
 *                      name="TypeName" type="xsd:QName"&gt;
 *                      &lt;xsd:annotation&gt;
 *                          &lt;xsd:documentation&gt;
 *                          The TypeName element is used to enumerate the
 *                          feature types to be described.  If no TypeName
 *                          elements are specified then all features should
 *                          be described.  The name must be a valid type
 *                          that belongs to the feature content as defined
 *                          by the GML Application Schema.
 *                       &lt;/xsd:documentation&gt;
 *                      &lt;/xsd:annotation&gt;
 *                  &lt;/xsd:element&gt;
 *              &lt;/xsd:sequence&gt;
 *              &lt;xsd:attribute default="text/xml; subtype=gml/3.1.1"
 *                  name="outputFormat" type="xsd:string" use="optional"&gt;
 *                  &lt;xsd:annotation&gt;
 *                      &lt;xsd:documentation&gt;
 *                       The outputFormat attribute is used to specify what schema
 *                       description language should be used to describe features.
 *                       The default value of 'text/xml; subtype=3.1.1' means that
 *                       the WFS must generate a GML3 application schema that can
 *                       be used to validate the GML3 output of a GetFeature
 *                       request or feature instances specified in Transaction
 *                       operations.
 *                       For the purposes of experimentation, vendor extension,
 *                       or even extensions that serve a specific community of
 *                       interest, other acceptable output format values may be
 *                       advertised by a WFS service in the capabilities document.
 *                       The meaning of such values in not defined in the WFS
 *                       specification.  The only proviso is such cases is that
 *                       clients may safely ignore outputFormat values that do
 *                       not recognize.
 *                    &lt;/xsd:documentation&gt;
 *                  &lt;/xsd:annotation&gt;
 *              &lt;/xsd:attribute&gt;
