QVT13 — Missing Identifier Syntax

Open Closed All
  • Key: QVT13-2
  • Legacy Issue Number: 10935
  • Status: closed  
  • Source: Model Driven Solutions ( Dr. Edward Willink)
  • Summary:

    The syntax of identifiers is undefined.

    The syntax for mapping clearly prohibits the use of a direction named 'where'.

    Suggest: identifier is an OCL simpleName, less the new reserved words (check default enforce
    imports map realize refines transformation uses where)

    Suggest: a string-literal may be used as an identifier to support awkward identifiers such as 'where'.

    Discussion

    OCL 2.3/2.4 clarified identifiers and strings so we can just exploit the OCL productions including it's underscore-prefixed-string identifier.

    OCL 2.3 also introduced String::_'+' so no special description is needed for a QVTr extension.
