Overview

IEEE document code (number with parts/subparts) Handles formats like:

802          - simple numbers
802.15.4     - dotted parts
C57.12.00    - prefix with parts
11073-10404  - dashed parts

      # 1. P-prefix or long part (>3 chars) → dash
      # 2. Letter prefix (except P) → dot
      # 3. Long number (5+ digits) → dash (IEC pattern)
