Extend the DseML to enable expressions to specifiy non-existing elements and attributes
It is not possible in the current version of the DseML to “talk about” model elements or non-filled properties that are not part of the input model. This is a severe limitation since knowledge about the out must be provided at the input side. For larger multi-step explorations, absence of this capability leads to convoluted code.
The resolution of this feature request is divided in two parts: The specification of non-existing model elements and model element properties. The latter is technically easier and can be achieved before the 2.15 release.
