\subsection{Members}
\label{sec:members}

The \xmlelement{members} element contains zero or more
\xmlelement{presence} elements, each describing a member of the group.
It is not necessary to provide the \xmlelement{basic} status for each
member.

\motivation{Since the extension namespace for \xmlelement{presence} is
restricted to \#\#other, we cannot include the PIDF
\xmlelement{presence} directly.}
