I found... just info here https://yaml.org/spec/ - So... maybe there is some RFC about YAML that I don't know - that's why I ask here
If anyone can clarify these doubts I would be happy for the feedback. This is just a question and not a request to create an RFC for YAML - in case there is no RFC for YAML available.
Hi all!
Context of doubt
