             Summary: Does a filter segment followed by a key predicate make sense?
                 Key: ODATA-1507
                 URL: https://issues.oasis-open.org/browse/ODATA-1507
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: ABNF
         Environment: Proposed
            Reporter: Heiko Theissen


ABNF rules allow the production
{code}
collectionNavNoCastExpr = filterExpr keyPredicate
{code}
which enables things like
{code}
Order('A')/Items/$filter(Product eq 'Sugar')(ItemNumber=2)
{code}
Is the {{$filter}} is redundant since a key predicate follows anyway? Or does this ensure that item #2 is returned only if its product is sugar?
