             Summary: Define propagation and (partial) overriding of annotations
                 Key: ODATA-811
                 URL: https://issues.oasis-open.org/browse/ODATA-811
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData CSDL
    Affects Versions: V4.0_ERRATA02
            Reporter: Ralf Handl
             Fix For: V4.1_WD01


We regularly face situations where we want to "propagate" annotations on a model element to all places where this model element is used/referenced, e.g. annotate an entity type and then have that annotation apply to all entity sets, or annotate a type definition and have that annotation apply to all properties or action parameters of that type.

An explicit annotation on one of the usage/reference points would then overrule/modify the annotation on the used/referenced construct.

The current specification text seems to implicitly assume this behavior, but doesn't explicitly state rules on
- where do annotations propagate to?
- how are structured annotations modified? PATCH semantics if only partially specified?
