Stan,

"In lieu" of a mandatory 8175 item is a pretty big change.  I don't think we want to go there.  I think the rest of the text is fine.

Point taken. So, you're good with the second sentence changing to "The latency Range Data Item MAY be carried in addition to the Latency Data Item." ??

Regards,
Stan

I agree with Rick on adding 'types'. So, I'll propose some text. Maybe this will help?

"The Latency Range Data Item MAY be carried in any message where the Latency Data Item [RFC8175] is allowed. The Latency Range Data Item MAY be carried in addition to, or in lieu of, the Latency Data Item."

Regards,
Stan

We have been fairly consistent in RFC8175 to refer to DLEP *messages*  I'm not sure adding 'types' helps...
