A List is a homogeneous set of ListItems.

The supported list types include:


An unordered list


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


An ordered list using increasing lowercase English letters


An unordered definition list


An ordered list using increasing Arabic numerals

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