> JSON Format 4.5.7 allows omitting the odata.id if it is identical to the canonical URL of the entity.
> URL Conventions 4.3.1 defines how the canonical URL is constructed BUT does not specify how the key predicate is to be constructed canonically.
> ABNF allows "synonyms" for the key predicate
> - for a single key property the key predicate may contain or omit the key property name
> - for multiple key properties no order is required for the key properties
> As a consequence a client cannot know how to construct the canonical URL from the entity set and key properties.
