the recommendation was what caused the norway problem. it now strongly recommends not to do this, and it says that a Yaml parser should use the core schema unless instructed otherwise. going against the recommendation while saying that you're yaml 1.2 compliant feels like an issue that should be raised with the parser to me. I've never run into this issue in practice though.

is there a parser that says that it's Yaml 1.2 compliant that uses that regex? I don't know of one.
