+Then when '''stream'''s are instantiated on the FlowSheet '''NComp''' will be a reference for '''NComp''' on the SubProcess.
+Then we can have parameters which are ''global'' inside of a given ''context''.
+If there is no '''intermediate''' declaration of the '''outer''' parameter, then it will be matched only on the '''FlowSheet''' and will works exactly
+as it is today.
 
 ||Who || Opinion || Why ||
 ||Rafael || '''agreed''' || proposed the change ||
 ||Paula || '''agreed''' || because this change gives more flexibility to the user ||
-||Arge || '''in doubt''' || if two streams are used in a model with different number of '''NComp''', is it possible to set '''stream1.NComp''' and '''stream2.NComp''' to different values in that model? ||

[[Color(red, please check the new explanation - it is not possible to have strems on the same model with different number of NComp using the outer command but it is possible for different models)]]||
