The JSON-LD CG has put in a tremendous amount of thought into these two
sentences. We did so before Peter and you raised the concern. We're now
revisiting the issue again since you two re-raised the concern. In fact,
it was the very first issue we discussed.

The set of definitions are not direct parallels to one another. The
JSON-LD data model isn't a direct parallel to the RDF data model. The
JSON-LD data model is more forgiving. Look at Section "3.1 JSON-LD Data
Model". You will notice that there isn't a single MUST in there. RDF has
a number of MUSTs in the data model. More here:
