UML14 — Definition of OclAny leads to problems when formalizing OCL

Open Closed All
  • Key: UML14-928
  • Legacy Issue Number: 2021
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: OclAny is essentially a type of all types. In particular,
    section 5.13 of the OCL specification implies that Set(OclAny)
    is a subtype of OclAny, from which a version of the Russell
    Paradox promptly follows.

    This needs to be clarified/resolved in the specification
