DocBook does not specify whether or not a symbol (such as - or /) is generated before the content of option, or what that symbol might be. Generating the text may or may not be desirable, but in either case, it is an interchange issue. See Appendix D, Interchanging DocBook Documents.


The following elements occur in option: text, abbrev, acronym, alt, anchor, annotation, biblioref, coref, date, emphasis (db._emphasis), firstterm (db._firstterm), footnote, footnoteref, foreignphrase (db._foreignphrase), glossterm (db._glossterm), indexterm (db.indexterm.endofrange), indexterm (db.indexterm.singular), indexterm (db.indexterm.startofrange), inlinemediaobject, link, olink, phrase (db._phrase), quote (db._quote), remark, replaceable, subscript, superscript, trademark, wordasword, xref.
