122 /**
123  * \brief API interface for XML-based plug-in persistence.
124  *
125  * The XML plug-in persistence is useful when a plug-in provides custom data handling. Normally, plug-in data
126  * is stored through the property sets (see \ref wwiseplugin_propertyset "PropertySet" and \ref wwiseplugin_objectstore "ObjectStore").
127  * However, a plug-in might provide its own custom handling. For complex interfaces, it might be worthwhile to use the
128  * \ref wwiseplugin_complexproperty "CustomData" interface. Loading and saving can then be done through this XML interface.
129  *
130  * The XML interface represents a cursor pointing to a node (element), alongside methods to navigate through
131  * the hierarchy.
132  *
133  * \aknote
134  * One unique XML interface is provided for both reading and writing XML. Depending on the instance being
135  * provided, it will allow reading or writing through this interface.
136  *
137  * It can either be a \ref ak_wwise_plugin_host_xml_reader_instance_v1 or a
138  * \ref ak_wwise_plugin_host_xml_writer_instance_v1.
