 *  &lt;xsd:complexType name="InsertElementType"&gt;
 *      &lt;xsd:annotation&gt;
 *          &lt;xsd:documentation&gt;
 *              An Insert element may contain a feature collection or one
 *              or more feature instances to be inserted into the
 *              repository.
 *           &lt;/xsd:documentation&gt;
 *      &lt;/xsd:annotation&gt;
 *      &lt;xsd:choice&gt;
 *          &lt;xsd:element ref="gml:_FeatureCollection"/&gt;
 *          &lt;xsd:sequence&gt;
 *              &lt;xsd:element maxOccurs="unbounded" ref="gml:_Feature"/&gt;
 *          &lt;/xsd:sequence&gt;
 *      &lt;/xsd:choice&gt;
 *      &lt;xsd:attribute default="GenerateNew" name="idgen"
 *          type="wfs:IdentifierGenerationOptionType" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *                 The idgen attribute control how a WFS generates identifiers
 *                 from newly created feature instances using the Insert action.
 *                 The default action is to have the WFS generate a new id for
 *                 the features.  This is also backward compatible with WFS 1.0
 *                 where the only action was for the WFS to generate an new id.
 *              &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 an Insert action.  The handle is included to
 *                 facilitate error reporting.  If an Insert action
 *                 in a Transaction request fails, then a WFS may
 *                 include the handle in an exception report to localize
 *                 the error.  If no handle is included of the offending
 *                 Insert element then a WFS may employee other means of
 *                 localizing the error (e.g. line number).
 *              &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *      &lt;xsd:attribute default="text/xml; subtype=gml/3.1.1"
 *          name="inputFormat" type="xsd:string" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *                 This inputFormat attribute is used to indicate
 *                 the format used to encode a feature instance in
 *                 an Insert element.  The default value of
 *                 'text/xml; subtype=gml/3.1.1' is used to indicate
 *                 that feature encoding is GML3.  Another example
 *                 might be 'text/xml; subtype=gml/2.1.2' indicating
 *                 that the feature us encoded in GML2.  A WFS must
 *                 declare in the capabilities document, using a
 *                 Parameter element, which version of GML it supports.
 *              &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *      &lt;xsd:attribute name="srsName" type="xsd:anyURI" use="optional"&gt;
 *          &lt;xsd:annotation&gt;
 *              &lt;xsd:documentation&gt;
 *        The optional srsName attribute is used to assert the SRS of the
 *        incoming feature data, which can be useful if the incoming feature
 *        data does not have an SRS declared for each geometry. If the
 *        srsName attribute exists on an &lt;Insert&gt; element, its value shall
 *        be equivalent to the value of &lt;DefaultSRS&gt; or any of the
 *        &lt;OtherSRS&gt; of the relevant feature types. If, however, the SRS is
 *        not supported, the WFS shall raise an exception as described in
 *        subclause 7.7. If the srsName is not specified on the &lt;Insert&gt;
 *        element, the WFS shall interpret this to mean that the feature
 *        data is given in the &lt;DefaultSRS&gt; list, except where an SRS is
 *        specified on the feature geometry. In this case, if the SRS for
 *        such a geometry is one of the &lt;DefaultSRS&gt; or &lt;OtherSR&gt; values
 *        for the respective feature types, it will be transformed as
 *        required before insertion. However, if the aforesaid SRS is not
 *        supported for the respective feature type, the entire transaction
 *        shall fail and the WFS shall raise an exception as described in
 *        subclause 7.7. If atomic transactions are not supported by the
 *        underlying DBMS, the WFS shall skip any feature with an
 *        unsupported SRS and continue
 *             &lt;/xsd:documentation&gt;
 *          &lt;/xsd:annotation&gt;
 *      &lt;/xsd:attribute&gt;
 *  &lt;/xsd:complexType&gt;
