Universität Bremen TZI YANG-CBOR (RFC 9254) defines YANG Schema Item iDentifiers (YANG SID), globally unique 63-bit unsigned integers used to identify YANG items. RFC 9595 defines ways to allocate these SIDs on the basis of IANA registries. The present specification employs these SID allocation mechanisms to allocate ranges with 100 000 63-bit SIDs each for each of the first 1 000 000 holders of IANA-registered Private Enterprise Numbers (PENs), as well as ranges with 10 000 32-bit SIDs each for each of the first 100 000 holders. // The present revision –03 is intended to address the feedback from // the CoRE Working-Group last call. Note that due to a regression // in the bib.ietf.org service (https://github.com/ietf-tools/bibxml- // service/issues/489 (https://github.com/ietf-tools/bibxml-service/ // issues/489)), the reference [IANA.enterprise-numbers] may come out // as "*** BROKEN REFERENCE ***" in some CI systems; this will // certainly be fixed in the course of further processing.
