/**
* This interface defines {@link ExtensionElement} implementations that contain other
* extensions. This effectively extends the idea of an extension within one of the
* top level {@link Stanza} types to consider any embedded element to be an extension
* of its parent. This more easily enables the usage of some of Smacks parsing
* utilities such as {@link PacketParserUtils#parseExtensionElement(String, String, org.jivesoftware.smack.xml.XmlPullParser, org.jivesoftware.smack.packet.XmlEnvironment)} to be used
* to parse any element of the XML being parsed.
*
* Top level extensions have only one element, but they can have multiple children, or
* their children can have multiple children. This interface is a way of allowing extensions
* to be embedded within one another as a partial or complete one to one mapping of extension
* to element.
