When argument ${../if/buffer:/params[0]/name} is the size of
the largest possible message in bytes
(the same value as member ${../if/config:/definition[2]/default/name} of type
${../if/config:/name}),
and ``MAXIMUM_PENDING_MESSAGES`` is the maximum number of messages
which can be stored in the message queue
(the same value as member ${../if/config:/definition[1]/default/name} of type
${../if/config:/name}),
and ``storage_area`` is a variable or structure member,
the expression
${../if/buffer:/name}( ${../if/buffer:/params[0]/name} )
storage_area[ MAXIMUM_PENDING_MESSAGES ]
shall declare an object of such a size that a pointer to it
is usable as value for member ${../if/config:/definition[3]/default/name}
of type ${../if/config:/name}.
