        The rules are not clearly defined in the contribution, but the intent was that, if metadata:type is not specified, the type is assumed to be string. So it is optional for primitive types, but its absence implies string.

        ATOM was intended to be self-describing. Currently you do not need metadata in order to interpret the payload. Not defining a specific meaning to metadata:type being missing for a primitive type would be the first case where metadata was required to interpret the ATOM payload.

        Proposal See summary The metadata:type attribute is required for properties with types other than Edm.String

        Accepted: https://www.oasis-open.org/committees/download.php/48411/odata-meeting-27_on-20130228-minutes.html#odata-200
        Description The metadata:type attribute is only required for complex properties with a declared type that has derived types.

        Using them also for primitive properties in the prominent example may mislead readers to think it is also required for primitive types.
