Yes, that's right, Markus. Also of relevance is that claims in the VC data model are "subject property value" statements (or "triples") that therefore bind properties and values to particular subjects. The selective disclosure scheme we described signs these statements directly (i.e., it does not break these statements up into their constituent parts), so you cannot erroneously recombine property-values with different subjects. -- Dave Longley CTO Digital Bazaar, Inc.
