             Summary: Access a property of the result of a non-composable function
                 Key: ODATA-1640
                 URL: https://issues.oasis-open.org/browse/ODATA-1640
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: CSDL JSON , CSDL XML
            Reporter: Heiko Theissen


Must a function be composable to allow access to individual properties of its returned value?

{code}
GET BillingDocument('90000090')/self.GetPDF()/BillingDocOutputDataBinary
{code}

The [specification|https://oasis-tcs.github.io/odata-specs/odata-csdl-json/odata-csdl-json.html#ComposableFunction] says

bq. A composable function can be invoked with additional path segments or key predicates appended to the resource path that identifies the composable function

and {{BillingDocOutputDataBinary}} is an "additional path segment".
