             Summary: Clarify handling of cycles in Extends for EntityContainers
                 Key: ODATA-733
                 URL: https://issues.oasis-open.org/browse/ODATA-733
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData CSDL
    Affects Versions: V4.0_ERRATA01
            Reporter: Ralf Handl
             Fix For: V4.0_ERRATA02


We do not explicitly forbid cycles in the Extends attribute, i.e. service A extends service B which extends service A.

Which does not seem to be a problem: Extends processing just has to stop when a container is reached that has already been processed because there's nothing new to add to the initial container. In the A extends B extends A example both services will publish the same entity sets etc.
