Textual material associated with a contributor.
Common Practice: Although a typical author comment might explain, for example, some facts about the circumstances under which a contributor wrote the material, during conversion the <author-comment> element can also act as an escape mechanism to take the content of any contributor-related elements not anticipated by the Suite.
<!ELEMENT author-comment
