The update reflects the split of roles - in the Ancient Days, the IETF
Executive Director and the head of the Secretariat were the same person,
and had no formal responsibility towards the IETF.
IMO, having to update our document to reflect these kinds of details
is unfortunate. It is clear that the intent should be that the
"secretariat function" (broadly defined) should make something happen
in this case.
In the post-IASA world order, Ray Pelletier is IETF Executive Director,
and reports to IAOC; the secretariat is headed by an employee of Neustar
Secretariat Services, and is under contract with ISOC.
To some extent, it's Ray's job/role to see that the above gets done by
the "secretariat function", though I don't think the details need to
be specified in detail in a standards track document.
Can we come up with generic language that doesn't get to specific job
titles? And that doesn't need updating if the details of the
individual roles internal to NSS change?
