We might want to postpone this until #510 is merged.

[smolkaj]

Generally LGTM.

Can you rebased to HEAD so the CI check passes? (See #513 for why it didn't pass in your run.)

[matthewtlam]

@smolkaj @chrispsommers I have rebased to HEAD and made the requested change from "hierarchy" -> "sequence". Please take a look

[jafingerhut]

LGTM. Chris, Steffen, you can merge this before the conversion to AsciiDoc if you really want to, but I doubt it is urgent. If you do, please let Davide and I know so we can make the corresponding change in the AsciiDoc version.

[smolkaj]

I think there is no particular urgency, as long as we don't forget about it.
Is there a rough target date for completing the Ascii oc conversion date?

As far as Davide and I are concerned, the Asciidoc version of the P4Runtime spec is done, subject to review and approval by others, i.e. by you and Chris Sommers, unless you can find another volunteer to review the PR: #510

For that PR, the ball is in your and Chris's court now, waiting for you.

[smolkaj]

Thanks for the nudge! I totally forgot about that (shame on me).

Definitely agreed that we should merge #510 first, then. I just left my review.
