Qualifiers for instance annotations: JSON Format

The CSDL specification states in http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part3-csdl/odata-v4.0-errata02-os-part3-csdl-complete.html#_Toc406009991 that:
"Metadata annotations can be used to define additional characteristics or capabilities of a metadata element (...). Instance annotations can be used to define additional information (...). Where the same annotation is defined at both the metadata and instance level, the instance-level annotation overrides the annotation specified at the metadata level."
The JSON format specification is incomplete because it does not allow overriding metadata-level annotations <b>that use a qualifier</b>, because qualifiers in instance annotations are not supported by the JSON format.
