Divisions of the edited text such as fragments, columns, chapters or versions in different languages.
Units of the text that are separated and usually numbered independently by epigraphers and papyrologists—including fragments, columns, sections, chapters, independent texts on a single stone, marks, stamps, or graffiti grouped together—should be divided and numbered on the same basis in EpiDoc. The use of XML should not change the need for dividing and numbering the text in a way that makes semantic and intuitive sense to the editor.
Each division containing a separate section of text should be wrapped in a separate <ab> inside a div with an type="textpart". It is often useful (although not obligatory) also to provide a subtype attribute naming the kind of subdivision of text being recorded here; subtype is not constrained, but common values might include "fragment", "column", "section", etc.
These units may, of course, nest in almost any combination. If there are non-hierarchical overlaps between units (e.g. sections and columns) then one unit has to be selected as the "top level" division, and the other broken up between the larger division. These smaller, broken divisions may be connected using the n attribute or a <link> element.
Where a unit within a single, continuous text need to be marked (for example, multiple blocks in a long relief text) the <milestone> element should be used instead to mark the point at which a break in the support occurs.
Where two distinct texts appear on one support (e.g. two distinct inscriptions on one stone), they can either be encoded in one single EpiDoc file or in two separate files. This is an editorial decision and EpiDoc does not dictate the use of one method over the other. If encoding the two texts in a single file, two separate divs with type of "textpart" should be used within the edition division. Each translation, commentary, bibliography etc. should also be divided into two textparts in order to record information separately about each text. If encoding the texts in two separate files, a link can be provided (or at the least a mention can be made) in the commentary directing the reader to the other text that appears on the same support.
