The XMPP Extensions Editor has received a proposal for a new XEP.
Title: Security Labels in PubSub
Abstract: This document describes an extension to XEP-0258 (Security Labels in
XMPP) to allow for the use of security labels in PubSub. This document describes
how security label metadata can be applied to the various elements
within PubSub, including nodes and items.

The XMPP Council will decide in the next two weeks whether to accept this
proposal as an official XEP.
