The NF reports
{{{

Error: Base class Modelica_LinearSystems2.DiscreteTransferFunction.Conversion.toDiscreteStateSpace

The sought-after function is defined [https://github.com/modelica/Modelica_LinearSystems2/blob/5485b6524c0ae9d8d9ecc48aef1db29d03714e6f/Modelica_LinearSystems2/DiscreteTransferFunction.mo#L1249 here]. 

The scope of {{{constructor}}} is encapsulated. However, [https://specification.modelica.org/v3.4/Ch5.html#simple-name-lookup Section 5.3.1 of the Specification] states that lookup is stopped for simple names, not composed using dot notation.
