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.
