@JamesNK , should I add a new section to this doc: Support for multi-segment parameters, reflecting what you provided in 7.0 preview 6 blog, or do you envision that being covered elsewhere?

[JamesNK]

There is a link to https://cloud.google.com/service-infrastructure/docs/service-management/reference/rpc/google.api#google.api.HttpRule from our doc which covers how to annotate the proto files.

I would eventually like to summarize annotating on our gRPC JSON transcoding doc.

This particular feature - multi-segment parameters - is unlikely to be used by many people. Don't need to talk about it.

@JamesNK Thanks! It looks like that is what you already covered annotating the .proto here correct?
Announcing gRPC JSON transcoding for .NET.

OK for me to get a PR started using your work from that blog and examples as a guide, or is this something you want to do yourself? If you do want me to start a PR, do you want me to expand at all on Would you want me to expand at all on HttpRule options? (I will leave out multi-segment parameters).

[wadepickett]

@JamesNK, Sorry for the needless noise, cancel that request on annotating. I realized simply covering it as a step as it is in this doc already (of course) and you were just wanting to summarize it better. I'll give that a shot given what you already have available with a PR for you to review.

Tracking the new summary for annotation in #26688. Closing this issue on multi-segment since we don't need it.
