An expression evaluating to an object
of type wodXMPP.
A String value.
This Property determines which capabilities are shown to the
server. Clients can implement various capabilities which they
support and they present it to the server. These capabilities are
usually exchanged with other clients so they can utilize them
between each other. Typical example would be 'HTML' capability -
when supported, two clients can exchange HTML decorated messages
instead of plaintext.
It depends on the server whether it will send your capabilities
to other clients on the network. You can see your contact's
too - if available.
