Hi,

The discussions on DAP should be ended this week as the SIPit is very close. All the participants that intend using DAP should accept a last version that should be available at latest on Monday morning. The accepted version should be used by the participants of SIPit.

I have the following modification and extention proposals:

* parameterization of compartment create:
this line is processed only if line-6 brings CREATE
line-6a = "state-memory-size" ":" *DIGIT CRLF
if there is no parameter, the application on its own may choose a state memory size
(it might be line-7 or whatever with shifting the other lines)

* need-response should have values: ("ANY" / "PREV" / "NO")
	- ANY: implementation choice
	- PREV: send back the previously uncompressed message of the compartment
		(This is very useful for testing if the message was decompressed correctly, as the other endpoint does not know what I sent.)
	- NO: need no response

* the header should not be arbitrary in case of a response. It should not be allowed to ask for a response in this case. It is most favourable that the message flow may be  entirely controlled by one of the endpoints!

* There should be another line to start/stop the dispatcher. Reason: there are tests even amongst the torture testst that use non-default values, and it is favourable to test all possible situations.

line-x = "dispatcher-op" ":" ( "START" / "STOP" );
line-y = "dispatcher-params" ":" *DIGIT ":" *DIGIT ":" *DIGIT
(may be inserted somewhere before the body line)
The three parameters - each of which are optional - are the cpb, dms and sms values for the dispatcher, respectively. If any of them is not specified or invalid, the application may choose a valid value instead.

With these modifications a whole series of tests may be run automatically.

Please, consider the above issues and comment them!
