Defines the external templates to use when publishing. When Templates are set in the publishing profile they take precedence over templates set at book level.
You can define a list of object replacement rules for the profile. During publishing the profile substitutes the object in the book with the preferred object. Using the replacement rules you can influence the look and feel by substituting the Media objects or Style objects. You can also replace objects used directly in the book contents such as: Title Page, TOC, TOF, Topic, Glossary and Index.
