DerDerivative of input (= analytic differentiations) 
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Defines that the output y is the derivative of the input u. Note, that Modelica.Blocks.Continuous.Derivative computes the derivative in an approximate sense, where as this block computes the derivative exactly. This requires that the input u is differentiated by the Modelica translator, if this derivative is not yet present in the model.
