Controlling number (enumeration) type

The style of numbers and symbols used in lists is applied by the publishing tool during processing. To use different number types, you must change the processing templates or routines.

By default, most DITA publishing tools render simple lists without bullets or numbers, unordered lists with bullets, numbered lists with Arabic numbers, and definition lists with the definition term as a hanging indent.

Second and subsequent level numbers in a nested ordered list are typically rendered following the format of 1. a. i..

If an alternative enumeration scheme is required, the processing routines must be modified. There is no specific enumeration type setting in DITA, as list presentation is considered to be form, not content.

If a particular list needs to be presented differently from other lists using the same list element, the outputclass attribute may be used in conjunction with customised processing routines.
