Changes to Numbering
In order to limit the knock-on impact of inserting or deleting text on the numbering of text that follows the change, the following conventions apply:(a) Where a new Paragraph is to be included in a Section, such that it would impact the numbering of existing text that would follow it, the Paragraph retains the numbering of the existing Paragraph immediately preceding it, but with the addition of an "A"; a second inserted Paragraph that follows immediately afterwards would be numbered with a "B", and so on.
For example, if a new Paragraph needs to be inserted after UG-3.1.6, it would be numbered UG-3.1.6A; a second new Paragraph would be numbered UG-3.1.6B, and so on. This convention avoids the need for renumbering existing text that follows an insertion. The same principle is applied where a new Section or a new Chapter needs to be inserted: for example, UG-3.1A (for a new Section), and UG-3A (for a new Chapter)(b) Where a Paragraph is deleted, then the numbering of the old Paragraph is retained, and the following inserted in square brackets: '[This Paragraph was deleted in April 2006.]' (The date given being the actual end-calendar quarter date of the deletion.) The same principle is applied with respect to Sections and Chapters.October 2010
Where many such changes have built up over time, then the CBB may reissue the whole Section, Paragraph, Chapter or even Module concerned, consolidating all these changes.October 2010
