the class GenericFeatureConverterWfs20 method marshal.

/**
     * This method will convert a {@link Metacard} instance into xml that will validate against the

     * @param writer
     *            the stream writer responsible for writing this xml doc
     * @param context
     *            a reference back to the Xstream marshalling context. Allows you to call
     *            "convertAnother" which will lookup other registered converters.
