Re: JSON-LD to QRcode

Yes, exactly - we include the very same identifiers (name, id) that had been included in the plain old non-QR version of the letters.  

We don’t sign over a student controlled key or DID (with which the student could later prove control), but could certainly do that later.  However, collecting a DID from the student complicates issuance quite a bit (like requiring that the student has a wallet that manages the student’s DIDs), and for the moment isn’t needed for these kinds of letters.
