  • Disposition: Resolved — QVT 1.0
  • Disposition Summary:

    (1) In Section 8.2.1.1 OperationalTransformation, replaces the sentence starting with "When an operational transformation refines a relational transformation, …" by the following sentence: "An operational transformation may be explicitly declared as the 'refinement' of a relational transformation. In that case each model parameter in the operational transformation corresponds to a typed model in the relational transformation. The enforced direction is the one corresponding to the output parameter of the operational transformation". Also remove constraint concerning enforcedDirection.
    (2) In Section 8.2.1.1 OperationalTransformation, removes the enforcedDirection property definition.

    Note: This resolution also implies removing the first constraint in Constraints section of 8.2.1.1 section.
