If the document is into volumes, each such volume shall restart the numbering sequence.

d. Document control numbers.

For hardcopy formats, this document may be printed on one or both sides of each page (single-sided/double-sided). All printed pages shall contain the document control number and the date of the document centered at the top of the page. Document control numbers shall include revision and volume identification as applicable.

e. Multiple (sub)paragraphs.

All paragraphs and subparagraphs starting with the phrase "This (sub)paragraph shall..." may be written as multiple subparagraphs to enhance readability. These subparagraphs shall be numbered sequentially.

f. Identifiers.

The letter "X" serves as an identifier for a series of descriptions. For example, the subparagraphs of paragraph 10.1.6.2 describes diagnostic procedures and is presented in the following structure:
