Impulse ports

[mondus]

The current version 1 spec does not support impulse ports (as defined in SpineML). Previously this was assumed to be supported via a coupled event and analogue port however this is syntactically unclear.

A suggestion is that we should either support impulse ports (an event with a payload value) or alternatively events should support an optional payload value.

[NineML-Committee]

The committee decided that the addition of one or multiple values to events should be supported as an option for event ports.

Example

<EventSendPort name="MyEventPort">
 <ValueSend name="srcname" source="mySV_par_or_Alias_or_OutputAnalog"/>
 <ValueSend .../>
</EventSendPort>

<EventReceivePort name="MyEventPort">
 <ValueReceive name="dstname" unit=""/>
 <ValueReceive .../>
</EventSendPort>

<PortConnection source="" destination="">
 <ValueConnection source="srcname" destination="dstname"/>
 <ValueConnection .../>
</PortConnection>

The ValueReceive named variables are only valid in the scope of the corresponding OnEvent.
