Place holder for the name of a contributor where the actual name is unknown or not disclosed
Design Note: Many journal tag sets model this element as an EMPTY place holder, which is used to generate “anon.”, “Anonymous”, or similar text. However, a few journal tag sets expect content for this element, with such text as “Anonymous but assumed to be Francis Bacon”. Therefore, as implemented starting with Tag Set Version 2.3, the element <anonymous> uses a mixed content model in this Archiving Tag Set, where it may be necessary to preserve content.
<!ELEMENT anonymous %anonymous-model; >
