Re: current signal-flow discipline

Marq,

Is clause 3.6.2.1 in error? For signal-flow disciplines the nature has 
to be potential. Current contributions on these nodes are not legal as 
the flow nature is not defined for signal-flow systems. There is a 
reference made to this in clause 1.3.3 also and the details for 
signal-flow is given in clause 1.3.4

cheers,
Sri
