Appendix: Standard tags for Adobe PDF documents
Heading and paragraph elements
Heading and paragraph elements are paragraph-like, block-level elements that include specific level headings and
generic paragraphs <P>. A heading element <H> should appear as the first child of any higher level division. Six
levels of headings <H1 to H6> are available for applications that don’t hierarchically nest sections.
Label and list elements
Label and list elements are block-level elements that are used for structuring lists:
•
List element <L> — Any sequence of items of similar meaning or other relevance; immediate child elements should
be list item elements
•
List item element <LI> — Any one member of a list; may have a label element (optional) and a list body element
(required) as a child
•
Label element <LBL> — A bullet, name, or number that identifies and distinguishes an element from others in the
same list
•
List body element <LBody> — The descriptive content of a list item
Special text elements
Special text elements identify text that is not used as a generic paragraph (<P>):
•
Block quote element <BlockQuote> — One or more paragraphs of text attributed to someone other than the
author of the immediate surrounding text
•
Caption element <Caption> — A brief portion of text that describes a table or a figure
•
Index element <Index> — A sequence of entries that contain identifying text and reference elements that point out
the occurrence of the text in the main body of the document
•
Table of contents element <TOC> — An element that contains a structured list of items and labels identifying those
items; has its own discrete hierarchy
•
Table of contents item element <TOCI> — An item contained in a list associated with a table of contents element
Table elements
Table elements are special elements for structuring tables:
•
Table element <Table> — A two-dimensional arrangement of data or text cells that contains table row elements as
child elements and may have a caption element as its first or last child element
•
Table row element <TR> — One row of headings or data in a table; may contain table header cell elements and
table data cell elements
•
Table data cell element <TD> — A table cell that contains nonheader data
•
Table header cell element <TH> — A table cell that contains header text or data describing one or more rows or
columns of a table
