SIDs are unsigned integers.  However, there are still languages that have a hard time with those.  And it helps if all SID deltas fit into a signed 64-bit integer.
So maybe limiting SIDs to the (non-negative) range of signed 64-bit integers is a restriction that makes sense.

https://github.com/core-wg/yang-cbor has three pull requests, but no issues.
(This apparently also happens to be the repo for the SID specification.)

Should we put up the issues there?
