Formatted as a displayed block. Titles are often repeated in several locations: for example, at the location where the object occurs, in the table of contents, and in running headers and footers.

DocBook does not offer any mechanism for indicating where a line break should occur in long titles. Titles are often repeated and no single line break is likely to be correct in all of the places where a title is used. Instead, you will have to rely on your processing system to provide a mechanism, such as a processing instruction, for identifying the location of forced line breaks.
