Subject: [OASIS Issue Tracker] (ODATA-825) AnnotationPath and Path expression: traversal of multiple collection-valued scalar or navigation properties


     [ https://issues.oasis-open.org/browse/ODATA-825?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Zurmuehl updated ODATA-825:
----------------------------------

    Description: 
When applying https://issues.oasis-open.org/browse/ODATA-481 we missed to adapt CSDL 14.5.2. (edm:AnnotationPath) and 14.5.12 (edm:Path).  Both sections restricts path expressions to contain at most one multi-valued  structural or navigation property.

Since an AnnotationPath traverses the object graph on structural level not on instance level, the cardinality of  structural or navigation properties is not relevant. The same holds true for a Path expression as long as it resolves to a term cast.
