Make $expand implicit if navigation properties are mentioned in $select or $aggregate
-------------------------------------------------------------------------------------

                 Key: ODATA-36
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-36
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData Protocol v1.0, OData URL Conventions v1.0
    Affects Versions: WD01
            Reporter: Martin Zurmuehl
            Priority: Minor
             Fix For: WD01


Currently clients need to repeat themselves when projecting on expanded entities:

GET http://services.odata.org/OData/OData.svc/Products?$select=*,Category/Name&$expand=Category

This could be reduced to 

GET http://services.odata.org/OData/OData.svc/Products?$select=*,Category/Name

because the client explicitly requests Category/Name, and the server can only satisfy that if it expands the Category.
