the class StreamGmlHelper method parseInstance.

/**
 * Parses an instance with the given type from the given XML stream reader.
 *
 * @param reader the XML stream reader, the current event must be the start
 *            element of the instance
 * @param type the definition of the instance type
 * @param indexInStream the index of the instance in the stream or
 *            <code>null</code>
 * @param strict if associating elements with properties should be done
 *            strictly according to the schema, otherwise a fall-back is
 *            used trying to populate values also on invalid property paths
 * @param srsDimension the dimension of the instance or <code>null</code>
 * @param crsProvider CRS provider in case no CRS is specified, may be
 *            <code>null</code>
 * @param parentType the type of the topmost instance
 * @param propertyPath the property path down from the topmost instance, may
 *            be <code>null</code>
 * @param allowNull if a <code>null</code> result is allowed
 * @param ignoreNamespaces if parsing of the XML instances should allow
 *            types and properties with namespaces that differ from those
 *            defined in the schema
 * @param ioProvider the I/O Provider to get value
 * @param crs The <code>CRSDefinition</code> to use for geometries
 * @return the parsed instance, may be <code>null</code> if allowNull is
 *         <code>true</code>
 * @throws XMLStreamException if parsing the instance failed
