This information is part of the Modelica Standard Library maintained by the Modelica Association.
This package contains interfaces of a set of functions and models used in the Modelica Standard Library that requires a tool specific implementation. There is an associated package called ModelicaServices. A tool vendor should provide a proper implementation of this library for the corresponding tool. The default implementation is "do nothing". In the Modelica Standard Library, the models and functions of ModelicaServices are used.
