FWIW, I wouldn't have read it like that. It says that the representation MUST contain a set of triples. But a set can be empty.

A possible clarification in the text would be to define that a container has a possibly empty set of members (and what kind of thing exactly can be in that set?), and the representation MUST contain triples corresponding to these members.

Best,
