Technical Corrections
The ESC Issues Tracking Database is a record of issues reported through the online issue reporting process regarding the CommonLine and CAM (Common Account Maintenance) documentation. This database is cumulative, intending to capture a history of all issues discussed by the ESC Advisory Teams. An issue may be a proposed text change to the document, a question concerning the content or intent of the document, or a conceptual change to a process. Some changes are minor in nature, requiring no discussion by the ESC Advisory Teams. These would include small cosmetic changes (like typographical errors) or direct answers to straightforward questions. This type of issue is not included in this database. The Issue Tracking home page has the most up to date corrections to the CommonLine and CAM file specifications.
