Overview

A List is a homogeneous set of ListItems.

The supported list types include:

:BULLET

An unordered list

:LABEL

An unordered definition list, but using an alternate RDoc::Markup syntax

:LALPHA

An ordered list using increasing lowercase English letters

:NOTE

An unordered definition list

:NUMBER

An ordered list using increasing Arabic numerals

:UALPHA

An ordered list using increasing uppercase English letters

Definition lists behave like HTML definition lists. Each list item can describe multiple terms. See ListItem for how labels and definition are stored as list items.
