           •  EntitySet/Singleton Name
           •  EntitySet key predicate name
           •  Property Name
           •  Type Name
           •  FunctionImport name/parameter name
           •  ActionImport name
           •  Bound function name/parameter name
           •  Bound action name
       3) Unqualified function call, including:
           •  Bound function call without namespace prefix
           •  Bound action call without namespace prefix
       4) Omitting Enum type name prefix for Enum value, including:
           •  Omitting Enum type prefix in binary operator
           •  Omitting Enum type prefix in entity set key value
           •  Omitting Enum type prefix in function parameter

Bug fixes

1. Fixes a bug that DataServiceCollection constructor runs into stack overflow when parameter T derives from a generic type of T.
2. Fixes a bug that Edm validator doesn't correctly report error when the Edm model contains dupped key properties.
