Tags are used in Adobe Acrobat to identify a contents value in a document so it can be read and interpreted by assistive technology. By tagging an object, we are assigning a hierarchical value to an element. For example: An <H1> tag is used for Headings Style 1 or the main heading for a section or chapter. <H2> is used for Heading Style 2, most commonly used for subsections.
