4.6.6 Other changes to specifications
Taught in 5. The Change Request, field by field (How standards actually get made, in depth), 9. Why the documents read the way they do (How standards actually get made, in depth), 4. The change request and the release (How standards actually get made, overview), 7. Reading either body's paper trail yourself (How standards actually get made, overview), 4. Looking it up yourself, and what the record will not tell you (How standards actually get made, quick start).
The Support Team may update a specification to correct purely editorial deficiencies brought to its attention. In this case, only the "editorial" field (third digit) of the version number shall be incremented. Such changes should be avoided if possible: normally, they should be held over for inclusion next time a technical change is made to the specification.
All such changes shall be clearly explained in the "change history" annex of the specification.
