- New Dialogs to define the association of expression to operations, to labelings and define input and output values/update.
- Initial implementation of the translation of SemanticExpressions to HLCL expressions for operations (without labeling and I/O considerations).
- Default subtypes for pairwise relations not correctly updated. The expressions remaind outdated if the subtype was not changed in the UI.
- Syntax attributes serialization and load fixed for the Metamodel. Method names/types corrected/added to match the attribute names and types on MetaElement and AttributeElement.
