Hi,

That's one thing (maybe the only thing) where we may need some discussion. 

When I wrote the text, I was also thinking about a normative STRONGLY RECOMMENDED.

I don't know whether MUST or SHOULD would make much sense, as we know there are endpoints that don't implement it.

Regards,

Christer
