SYM_ — clarification needed for the fromLibrary attribute

In the SysML-Modelica Transformation Specification (http://www.omg.org/spec/SyM/1.0/Beta1/PDF/), the attribute fromLibrary for the stereotype «modelicaClassDefinition» is not sufficiently clearly defined (Section 8.2, page 10). The spec mentions that some details (e.g. "value properties and parts") can be omitted when using the fromLibrary tag, but the spec is not sufficiently precise as to which details exactly can/should be omitted and which should still be retained. Since this is a construct that will likely be used extensively, it should be defined more precisely.

The identified issue does not relate to the mapping of language constructs between SysML and Modelica but rather to a user- and tool-specific usability aspect of the transformation. The issue therefore does not identify a problem with the specification. Additionally, the “fromLibrary” attribute of the «modelicaClassDefinition» stereotype will be removed since it does not relate to the mapping of language constructs between SysML and Modelica.
