      Add a property ErrorResponses to the Capabilities terms InsertRestrictions, UpdateRestrictions, DeleteRestrictions, ReadRestrictions, and OperationRestrictions:

      <Property Name="ErrorResponses" Type="Collection(Capabilities.HttpResponse)">

      Description

      Jeff Wight proposes to add a term that allows describing possible code values in OData error responses, see https://lists.oasis-open.org/archives/odata-comment/201510/msg00019.html

      Example:

      <Annotation Term="Core.ErrorCodes">
  <Collection>
    <Record>
      <PropertyValue Property="HttpMethod" String="GET" />
      <PropertyValue Property="HttpStatusCode" String="400" />
      <PropertyValue Property="ODataErrorCode" String="QueryFilterFunctionNotSupported" />
      <PropertyValue Property="Description"
 String="This error indicates that a request was made with a filter function that isn’t supported on this entity set. Please refer to the Capabilities.FilterFunctions annotation on this entity set for a list of supported functions, and the exact error message for which function usage triggered this error." />
    </Record>
  </Collection>
</Annotation>

      Definition

      <Term Name="ErrorCodes" Type="Collection(Core.ErrorCodeType)" AppliesTo="EntitySet Singleton ActionImport FunctionImport Action Function">
  <Annotation Term="Core.Description" String="Describes possible error codes in OData responses" />
  <Annotation Term="Core.LongDescription" String="The list need not be complete. It may be used to generate API documentation, so restricting it to the most common and most important errors may increase readability." />
</Term>

<ComplexType Name="ErrorCodeType">
  <Property Name="HttpMethod" Type="Edm.String">
    <Annotation Term="Core.Description" String="Request verb of the HTTP request, e.g. GET, POST, PATCH, DELETE" />
  </Property>
  <Property Name="HttpStatusCode" Type="Edm.String">
    <Annotation Term="Core.Description" String="HTTP status code of the response, e.g. 400, 403, 501" />
  </Property>
  <Property Name="ODataErrorCode" Type="Edm.String">
    <Annotation Term="Core.Description" String="Language-independent, machine-readable OData error code" />
  </Property>
  <Property Name="Description" Type="Edm.String">
    <Annotation Term="Core.Description" String="Human-readable description of the error situation" />
  </Property>
</ComplexType>
