             Summary: Path evaluation for annotations targeting annotations
                 Key: ODATA-1420
                 URL: https://issues.oasis-open.org/browse/ODATA-1420
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
            Reporter: Heiko Theissen


[OData-CSDL, section "Path evaluation"|https://docs.oasis-open.org/odata/odata-csdl-xml/v4.01/cos01/odata-csdl-xml-v4.01-cos01.html#sec_PathEvaluation] does not specify rules for annotations that target another annotation.

Imagine an annotation term {{PAngV.PriceSection2}} whose value is an amount.
{code:xml}
<EntityType Name="SalesOrderItem">
 <Property Name="Pieces" Type="Edm.Int"/>
 <Property Name="Price" Type="Edm.Decimal"/>
 <Annotation Term="PAngV.PriceSection2">
  <DivBy>
   <Path>Price</Path>
   <Path>Pieces</Path>
  </DivBy>
  <Annotation Term="Measures.ISOCurrency">
   <Path>Price/@Measures.ISOCurrency"</Path>
  </Annotation>
 </Annotation>
</EntityType>
{code}
This entity set computes the {{PAngV.PriceSection2}} as an annotation and wants to annotate this annotation with the corresponding currency. I would expect the evaluation of the path {{Price/@Measures.ISOCurrency}} to follow the rules for "annotations embedded within a structural or navigation property of an entity type or complex type", because the "outer" annotation has a primitive type.

This should be clarified in the specification.
