Sorry @Elisabeth-Ericsson , I was traveling because May 1st is a holiday here and did not see this PR. I changed the file and now there are merge conflicts.

Although, I am not sure about the HTTP "decoration". I left those out because I wanted to focus on the purpose parts.
And I want to remove all two-purpose examples for now, because I think those lead to discussions I currently don't want to focus on.
I am astonished that I missed the missing sub field, because I copied the examples from some spec, thinking that they must be correct.

Not sure, how to proceed with this PR.

1. close it and create smaller ones, that e.g. add sub?
2. resolve merge conflicts and merge?

WDYT?

I believe the RFC9101 request object examples should have the following claims, as per RFC7519:

exp: Expiration Time Claim
nbf: Not Before Claim
iat: Issued At Claim
jti: JWT ID Claim
