             Summary: Extend definition of edm:path expression
                 Key: ODATA-786
                 URL: https://issues.oasis-open.org/browse/ODATA-786
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData CSDL
    Affects Versions: V4.0_ERRATA02
         Environment:   
            Reporter: Martin Zurmuehl
             Fix For: V4.1_WD01


Currently we can annotated many csdl elements via embedded annotations or via the edm:Annotations element. 
In the edm:path expression definition we had specified how a path expression is evaluated, if the annotation targets a entity container, entity set, entity type, complex type, navigation property of a structured type, or a property of a structured type.
We should check for any other csdl element how the path expression could be evaluated, if an annotation targets it (if it make sense); e.g. if we target an edm:FunctionImport we can define specific path segments to fork to the parameters or to the ReturnType.

With the extension of the edm:path we will automatically extend the definitions of the csdl elements based on edm:path like edm:propertypath.
