The OASIS Technical Advisory Board (TAB) has published "Keyword Guidelines for OASIS Specifications and Standards."
This short document is intended to assist OASIS authors and editors in the proper use of normative keywords (RFC2119 or ISO). It is written
to assist editors in using keywords consistently so that the meaning of a specification is clear and unambiguous, ensuring consistent implementation of its normative content.
You can find the document at
https://www.oasis-open.org/policies-guidelines/keyword-guidelines. It is linked from the OASIS Policies and Guidelines
page at https://www.oasis-open.org/policies-guidelines and from the TC Administration page at
Our thanks to the members of the TAB for their work on this document.
