I suppose that the impending expiration of the -02 also had a role.

I was confused by the diffs from -02 since almost all the changes were
things we had already seen in the post-107 virtual meeting.  I suppose that
the document that we discussed at that time has not been posted until now.

I will present my plans for an implementation during the meeting/call.

If you are requesting a speaking slot at that meeting and it seems as if
you are, you need to send me something that tells me what you intend to
talk about and how much time you intend to take.

Normally "plans for an implementation" might be an OK description but in
this case the specific attributes you intend to implement have never been
described, so I'll need some clarification on that, as would anyone who
might be interested in interoperating with your proposed implementation.

No additional changes were made at this time.

In the eleven months since the -00 was published, there has been very
limited progress toward describing the substance of the proposed attributes
and I think the working group will want to hear about your plans to make
progress in that regard. The need for that description was made clear at
the post-107 meeting.

Also, you agreed to work on the nvme/pNFS document and we will need a
progress report on that effort.

Thank you
