Right! Sorry, the confusion comes from 4 and 8 which are not an HTTP
request/response pair.
They are a payment request/response pair and the labels make that confusing.

What tool are you using for this diagram, I can have a stab at a new
version.

Really? I'm not crazy about that but I'd like to hear what the group thinks.

Perhaps we can use a static snapshot that we edit inline and then push back
to the shared glossary when it stabilizes?

PaymentRequest is very agnostic in this regard.
It feels like HTTP is very pull-focused in comparison.

I will not object to publishing if the issues in the text are also in the
issue list and any issues in the list are also in the text as markers (if
appropriate). This is roughly the same process we went through with Payment
Request and Payment Method Identifiers so I feel like we're being
consistent.

I have asked the group to submit their issues before Tuesday.

Bare in mind though that we are doing what we agreed we'd not do and that
is ask the group to dedicate time to this work ahead of the Payment Apps
work which is higher priority. I am certainly keen to move this forward but
not at the expense of work on Payment Apps.
