The main benefit of DITA2Go list styles is the ability to use any characters as bullets, rather than the limited assortment supported by CSS; see §7.6.6.1 Assigning properties to list formats for HTML list styles.
DITA2Go list styles are the default for RTF output. For HTML-based output, specify the appropriate settings described in §30.10.2 Converting list formats to HTML list styles.
To specify margins and indentation for DITA2Go list styles:
[ListOptions] LevelMargin = 12pt NumberOutdent = 8pt BulletOutdent = 6pt
To specify numbering for ordered lists, see §8.5 Configuring output numbering properties. To specify bullets for unordered lists, define number formats with stream=none and form= a Unicode value; see§8.5.5.4 Specifying symbols for bulleted lists.
