<td colspan="5" class="print">With "-&gt; value" acc. to cl. 22.2.2 in a
receive statement a value can be stored in a variable. This concept
shall be enhanced for altsteps as well:<br />
It shall be possible to declare a return value for an altstep which can
be assigned to a variable with "-&gt; value".<br />
<br />
NOTE: as for receive statements there is no need to assign the receive
value to a variable directly with the ":=" operator (at least from
MCC160's point of view).<br />

<td class="print-category">Additional Information</td>
<td colspan="5" class="print">Use case:<br />
<br />
Especially with SIP we cannot fully check the correctness of a message
by means of receive templates but need to do further checking after we
have received a message; furthermore we may need to respond to requests
immediately and but we also may need to refer to the content of messages
later on.<br />
 Now - we have scenarios where some requests need to be received in any
order or some of them are even optional.<br />
 =&gt; it is useful to have a set of altsteps to receive a single
Message, check it and respond to it.<br />
<br />
 So - what I would do when possible is e.g.<br />
 alt {<br />
   [] a_ReceiveCheckRespondToMessage1(...) -&gt; value v_Message1
{...}<br />
   [] a_ReceiveCheckRespondToMessage2(...) -&gt; value v_Message2
{...}<br />
   [] a_ReceiveCheckRespondToMessage3(...) -&gt; value v_Message3
{...}<br />
   ...<br />
   [] t_Timer.timeout {...}<br />
 }<br />
<br />
