Signed HTTP Exchanges use case

Dear Jeffrey,

My colleagues at GS1 and I have been looking at your Signed HTTP
Exchanges work which looks like a good fit for a use case we have - but
I need to do a sanity check, please. Here's a simple example of the kind
of use case we're tackling:

I scan a barcode on a product using a mobile phone app.

The app adds the scanned number (we call it the GTIN) into a template
URL{gtin}. is a server that conforms to a GS1 standard (that we're
writing at the moment) and redirects the request to a resource on the Web.

Given that anyone can build and operate a GS1 conformant resolver, we
need a method of distinguishing between a redirection link authorised by
the product manufacturer and any other link a resolver might offer.

Adding just a little complexity, actually we want resolvers to offer
multiple links with link relation types like "recipeWebsite" and
"instructionManual" - and those links will be exposed in an HTTP Link

It looks as if your Internet Draft provides exactly the kind of thing we
need - the ability for a brand to sign that HTTP exchange, saying "yes,
we authorised these links" - even though they're not the ones operating
the resolver.

If it is the case that your I-D is a suitable method for achieving this,
would you consider adding a further use case to that effect in Appendix A?
