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.

This document is a product of the Concise Binary Object Representation Maintenance and Extensions Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
