Clarify that "VALID" in the test outputs is not the only permitted value

Comment Post #291091 When the input is a valid Roman number, the output does not need to be specifically the string "VALID". From the first bullet point of the Output section, you just need to "output a consistent value" which "must not be one of the strings from the list of 50". Hopefully this saves you some bytes.

Change output requirements to require use of the 50 strings

Comment Post #291002 Another possible challenge: Given a string of Roman numerals, output either "valid" or a string from the list of 50 that proves it invalid. This may involve the Kolmogorov complexity challenge as a subchallenge. Is this good or bad?

Comment Post #291002 As written, the challenge is simply to validate a string of Roman numerals. I suspect that in most languages the golfiest way will be regex, and the list of 50 substrings will not be used. As such, they are irrelevant background info about Roman numerals, rather than being part of the challenge. I'm ...
