ANSWER: CWE-79
The identifier must be one of the 30 listed above. Any other text is ignored.
Optionally add a second line saying how likely you think that answer is to be right, between 0 and 1:
CONFIDENCE: 0.85
Confidence is recorded and reported, never scored. Leaving it out costs nothing; giving it lets the report say whether your certainty tracks your accuracy.
