@handrews ; Most of the job has been done

there is one remaiing
https://github.com/OAI/OpenAPI-Specification/blob/v3.1.1-dev/versions/3.1.1.md?plain=1#L1991

but still we could close it ... or fix the last one

@LasneF thanks for checking! Those two are actually the example field in the Media Type Object, which supports both example and examples, which are distinct from the JSON Schema examples or the OAS legacy Schema Object example 🤦

The whole mess has been explained better with PR #3895, so I'm going to close this as it should be as clear as it gets at this point.

I did search 3.1.1.md for /examples?"?:/ and didn't find anything that looked incorrect to me.
