Refer to attributes from Match and Apply classes (for DSLTrans and SyVOLT) not as strings

[levilucio]

• Go to the solution "ExFamToPerson", rule City2TownHall
• In the match model, the attribute C2TH_City is implemented by the MatchAttributeString class that contains an atom which is a String
• The displayed attribute should refer to an attribute the class refers to, instead of just a string. A TVPropIDRefExpression is already there for this purpose so that scoping is also possible, as is done for the language concepts.

The references to attributes work well when the rule is defined inside a Transformation concept instance. However, rules can also exist at the top level of the model and be referred to from the transformation. In these rules the scoping does not work properly.

• Go to any rule at the top level.
• Try to build a reference to an attribute from a Class. The scoping refers to all imported languages.
• It should only refer to the input or output languages imported by the transformation.
• Note that match elements of a class are scoped by the concepts of the input language, while apply elements of a class are scoped by the concepts of the output language.
