Parts of a Main Title: A simple main title should be tagged using the <main> element. If the main title has a label or subtitles, the <main-title-wrap> element is used to hold all the main title components together.
Tagging the Title of a Standard: The title of a standard may be tagged as a whole (<full>) or divided into introductory, main, and complementary components:
  • Introductory: The optional introductory title(s) are the initial part(s) of a standard’s title, which typically indicate the broad context of the standard or of a sponsoring group or provide a stock phrase, such as “Standard Specification for”. Each introductory title may contain only text or include its own label and subtitles.
  • Main: The optional main portion of the standard’s title, which typically indicates the principal subject of the standard. A main title may contain only text or include its own label and subtitles.
  • Complementary: The optional complementary title(s) are the final part(s) of a standard’s title. Complementary titles follow the <main> title and typically provide details concerning which particular aspect of the general topic is treated by the standards document. Each complementary title may contain only text or include its own label and subtitles.
