As noted in issue #47 there were some improvements
The CSAF field is now optional (like "Acknowledgments" and "Hiring") so the recommendation is removed. The errors remain, if the field is listed with an issue it will throw an error.
The "multiple_csaf_fields" has been moved from a notification to a recommendation.
The "no_csaf_file" text has been updated to be more clear.
