Ralf Handl updated ODATA-960:
-----------------------------
Description:
We'd like to use a Singleton to control capabilities of an entity set, e.g. use a property of a singleton to tell whether the authenticated user is allowed to create new entities in a given entity set. This means we'd like to use a Path construct for the value of @Capabilities.InsertRestrictions/Insertable, e.g.
<Annotations Target="My.Container/SalesOrders">
<Annotation Term="Capabilities.InsertRestrictions">
<Record>
<PropertyValue Property="Insertable" Path="/My.Container/Me/Permissions/CanCreateOrders" />
</Record>
</Annotation>
</Annotations>

</Annotations>
Proposal:
Extend Path syntax to allow absolute paths that start with a top-level model element (schema child).
Natural syntax would be a path starting with a forward slash.
Note: current "relative" paths can already start with a type-cast segment which is a qualified type name, so the / prefix or something similar is needed to distinguish "absolute" paths.

Extend Path syntax to allow absolute paths that are interpreted starting at the entity container.
Natural syntax would be a path starting with a forward slash.
