Body
1. Description

The IETF NETMOD working group would like to thank you for your LS [1].
We are sorry the documents [2][3] shared in our previous LS [4] are not seen as
suitable to be used in 3GPP SA5 specifications. While these documents have
progressed reasonably far through the IETF publication process, there is still
opportunity for change. The IETF is contribution driven. The NETMOD working
group encourages engagement on the working group mailing list [5] and
contributions to future working group meetings that propose any changes that
might make the documents better suited for use in SA5 specifications.

2. Upcoming Meetings

IETF 125, 14 - 20 March 2026, Shenzhen, China
IETF 126, 18 - 24 July, Vienna, Austria
