The XMPP Extensions Editor has received a proposal for a new XEP. Title: Security Labels in XMPP
Abstract: This document describes the use of security labels in XMPP. The document specifies how security label metadata is carried in XMPP, when this metadata should or should not be provided, and how the metadata is to be processed. URL: http://www.xmpp.org/extensions/inbox/security-labels.html The XMPP Council will decide at its next meeting whether to accept this proposal as an official XEP.
