  Do Variable.Array, Variable.Constant, and Variable.Observed differ in more than just different default settings of the isReadOnly and ObservedValue property?

  I would like to use the convenient constructor for jagged arrays of Variable.Constant to yield an observed Variable.

  The following code works:

      let varArray= (Variable.Constant<Discrete>((myNestedArray:_[][]), outerRange , innerRange))
      do varArray.AddAttribute(valueRange)
      do varArray.IsReadOnly <- false

  later I can change the value by

      do varArray.ObservedValue<- otherNestedArray

   

  Is there a difference between this varArray and an array that is created via the Variable.Observed constructor?

   

  I guess I can create an analogous variable via Variable.Array

  let varArray = (Variable.Array<_>(Variable.Array<Discrete>(innerRange), outerRange))

  and call

      do varArray.ObservedValue<- otherNestedArray

  Right?
