Change numbering styles for ordered lists

Ordered lists (ol) are usually numbered in XHTML output using numerals. If you want to change the numbering to alphabetical, do the following:
  1. Define a custom outputclass value and set it as an attribute of the ordered list, as in the following example:
    <ol outputclass="number-alpha">
        <li>A</li>
        <li>B</li>
        <li>C</li>
    </ol>
  2. Add the following code snippet in a custom CSS file:
    ol.number-alpha{
        list-style-type:lower-alpha;
    }
  3. Edit the DITA transformation scenario and configure the following parameters:
    • args.css parameter to reference the custom CSS file appended earlier
    • args.copycss parameter set to true.
