The Concise Data Definition Language (CDDL), standardized in RFC 8610, provides "control operators" as its main language extension point.

The present document defines a number of control operators that were not yet ready at the time RFC 8610 was completed: , , and for the construction of constants; / for including ABNF (RFC 5234 and RFC 7405) in CDDL specifications; and for indicating the use of a non-basic feature in an instance.

For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 8729.
