| Quote | An inline portion of text attributed to someone other than the author of the surrounding text. The quoted text should be contained inline within a single paragraph.

| Subdivision | Encloses content typically perceived as a sub-division inside a block level structure element. |
| Table | A two-dimensional logical structure of cells, possibly including a complex substructure. Supported in PDF/UA-1. |
| TableBody | A group of TableRow structure elements that constitute the main body portion of a table. Internal to a Table structure. Supported in PDF/UA-1. |
| TableDataCell | A table cell containing content that is part of the table's content. Internal to a Table structure. Supported in PDF/UA-1. |
| TableFooter | A group of TableRow structure elements that constitute the footer of a table. Internal to a Table structure. Supported in PDF/UA-1. |
| TableHeader | A group of TableRow structure elements that constitute the header of a table. Internal to a Table structure. Supported in PDF/UA-1. |
| TableHeaderCell | A table header cell containing content describing one or more rows, columns or rows and columns of the table. Internal to a Table structure. Supported in PDF/UA-1. |
| TableOfContents | A list made up of table of contents item entries (TableOfContentsItem) and/or other nested table of contents entries (TableOfContents). A TableOfContents entry that includes only TableOfContentsItem entries represents a flat hierarchy. A TableOfContents entry that includes other nested TableOfContents entries (and possibly TableOfContentsItem entries) represents a more complex hierarchy. Ideally, the hierarchy of a top level TableOfContents entry reflects the structure of the main body of the document. Supported in PDF/UA-1. |
| TableOfContentsItem | An individual member of a table of contents. This entry's children may be any of the following structure types:
Supported in PDF/UA-1. |
| TableRow | A row of TableHeaderCell cells or TableDataCell cells in a table. Internal to a Table structure. Supported in PDF/UA-1. |
