Extensions
The XMPP Standards Foundation or XSF (formerly the Jabber Software Foundation) is active in developing open XMPP extensions. However, extensions can also be defined by any individual, software project, or organization. For example, Google has defined a number of non-XSF extensions, which are used in Google Talk and Google+ (e.g., for signalling related to Google Hangouts). Another example is the federation protocol in Apache Wave, which is based on XMPP.

Famous quotes containing the word extensions:
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
“If we focus exclusively on teaching our children to read, write, spell, and count in their first years of life, we turn our homes into extensions of school and turn bringing up a child into an exercise in curriculum development. We should be parents first and teachers of academic skills second.”
—Neil Kurshan (20th century)
