Why are the style names short and obscure?
After much deliberation we decided to use short style names like ‘h1’ for a top-level heading, and li2b for a second level bulleted list item.The set of style names is designed to be different to those that ship by default with major word processors in order to emphasize that this is a self-contained system. For example, a first level heading is called h1, rather than Heading 1 in Word or OpenOffice.org while a first level bulleted list item would be li1b for “list item, level 1, bullet”.In the default style-sets that come with other word processors this kind of list item might be “List 1” in OpenOffice.org, or “List Bullet 1” in Word.
