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.
