/**
|
|
* Interface to represent extension elements.
|
|
* <p>
|
|
* An extension element is an XML subdocument
|
|
* with a root element name and namespace. Extension elements are used to provide
|
|
* extended functionality beyond what is in the base XMPP specification. Examples of
|
|
* extensions elements include message events, message properties, and extra presence data.
|
|
* IQ stanzas have limited support for extension elements.
|
|
* <p>
|
|
* This class is used primarily for extended content in XMPP Stanzas, to act as so called "extension elements". For more
|
|
* information see <a href="https://tools.ietf.org/html/rfc6120#section-8.4">RFC 6120 § 8.4 Extended Content</a>.
