Description

Given a type hierarchy of X.F.A where X.F is specified as Permission="read" and X.F.A is specified as Permission="write".

There is disagreement about whether X.F.A may be written. Our assertion is that permissions may be removed, but not added when moving towards the leaves in a type hierarchy, and thus a write to X.F.A would fail. Others are asserting the opposite.

The documentation within Org.OData.Core.V1.xml needs to be clarified to make the propagation policy clear.

Research direction

Open Org.OData.Core.V1.xml and locate the documentation for Permission propagation through type hierarchies. Review the X.F and X.F.A example and the surrounding permission definitions, then resolve the stated disagreement with maintainers before updating the wording. Done means the documentation explicitly describes the propagation policy and makes the example's outcome unambiguous.
