§1-108.   Special Numbering Problems.
   1.   Addition of New Units Between Existing Units. If it becomes necessary to introduce a new Chapter, Part or Section between existing Chapters, Parts or Sections, the new Chapter, Part or Section shall be designated by the addition of a capital letter suffix to the preceding Chapter, Part or Section number. Thus, a Chapter introduced between Chapters 5 and 6 would be Chapter 5A and Sections in that Chapter would be numbered, for instance, “§5A-101.” If it becomes necessary to introduce a Part between existing Parts 5 and 6 the new Part would be Part 5A and Sections in that Part would be numbered, for instance, “§5-5A01.” A new Section introduced between existing Sections 5 and 6 would be “§5-105A.” When a number of new Parts or Sections have been introduced the Chapter or Part shall be renumbered.
   2.   If it becomes necessary to introduce a Subsection between Subsections, for instance, Subsections .5 and .6, the new Subsection would be numbered Subsection .5-A.
   3.   If it becomes necessary to introduce a unit smaller than a Subsection between existing units, the entire Subsection shall be revised and renumbered.
   4.   Vacated Numbers. Whenever a number is vacated by a revocation or repeal, the remaining elements in the overall unit shall retain their old numbers until the overall unit is completely revised. Prior to revision, the vacated number may be marked: “[Reserved].”
