I'm not sure I see the value in supplying an optional value. Shouldn't the CSV validator easily be able to perform some checks if a CSV value is present, and skip them if not present?

HI @estroz, @jmrodri, @fabianvf

Now we have here only the validator impl.

Before this goes in, I would really like to see docs about how this value is used in the api repo, and have them referenced in SDK docs. Otherwise we're just adding some nebulous, obscure feature.
