Changes made:
Additional Modelica meta-model includes opaque expressions (Modelica-Opaque)
The old model has been renamed to Modelica-OMC
The conversion from Modelica abstract syntax (.moast) to Modelica-Opaque occurs in 2 steps:
From .moast to Modelica-OMC (current transformation)
To Modelica-Opaque by using a QVT filter to add the opaque expressions (with Java un-parsing code as black boxes)
The QVT transformation is SysML4Modelica and Modelica-Opaque is now bi-directional
The generation of the Modelica concrete textual syntax starts from the Modelica-Opaque XMI
