Remarks

This enumeration provides a comprehensive list of structural element types that can be used to describe the logical structure of a PDF document. These types are commonly used in tagged PDFs to improve accessibility, enable content reflow, and provide semantic meaning to document elements. Each value corresponds to a specific structural role, such as headings, lists, tables, or annotations. For example, H1 through H6 represent heading levels, while Table, TR, TH, and TD represent table structures.
