The reason is that we use that format here for our daily use and thus generate all documents in that format. A date has been placed in the header or footer in the right hand corner of each page to indicate when a section was last updated. The section number is a five digit number in conformance with CSI recommendations. For other disciplines, there will be no letter. The section number is followed by the section title on the next line.
All information is capitalized, in bold print, and centered on the page width.
Two blank lines follow this information before any other text. Each part of the three-part specification is identified in bold, capitalized, wide spaced letters centered on the page. A single blank line follows the entry before beginning a heading. Each heading within any of the three parts is left-justified, capitalized, and in bold print. This heading is set off somewhat by having a blank line before the entry.
