• Also a fifth note type: can be undefined or user defined; represented by a "n" icon (for note).

fluidity of the writing process

• allows editors to distinguish within a particular witness bibliographic features as holograph and/or typescript emendations and erasures;

• feature controlled by a combination of XSLT and CSS;

• Utilise XSLT to transform the elements, leaving display protocols to the CSS.

• allows for editorial control of display via the CSS (presumption that most editors would find it easier to manipulate CSS)

Element matching in previous versions

• line matching across a witness set highlights parallel-encoded units across versions;

• Matches on <l>, <p><seg>, <s>, <c>, <mod>, <closer>, <opener>, and <epigraph>;

• For display purposes the entire line across witnesses is highlighted
