-Add text that warns implementers using this specification in selective
-disclosure schemes that graph structure might reveal information about the
-entity disclosing the information. For example, knowing that a blank node
-contains two triples vs. five triples might reveal that the entity that
-is disclosing the information is a part of a subclass of a population,
-which might be enough to disclose information beyond what the discloser intended to
