[sparkplug-wg] Specification v2.2, Typo in Figure 4 ?

[Zaiming Shi <zmstone@xxxxxxxxx>]

Hi all.

While studying the specification, I'm a bit puzzled by Figure 4, EoN node Session Establishment flow chart (pasted a screenshot).

If I understand it correctly:

* Step 2 should be a "PUBLISH" (but not "SUBSCRIBE") of the NBIRTH message

* Step 3 should be a "SUBSCRIBE" (but not "PUBLISH")

Otherwise, I may need some help to understand how these two steps work.

Regards
