List item: Identifies an item in a list.
<list [id=id]> * List item * List item <\list>
Or:
<list order> <item id=name1>List item <item id=name2>List item <item id=name3>List item . . . <\list>
The shorthand form, which is an * (asterisk), is almost always used.
The long form allows you to cross-reference an item in a list. You can only cross-reference items in an ordered (numbered) list. The automatically assigned item numbers are used in the cross-reference text (which HelpTag substitutes for the <xref> element). Unlike a number, a bullet character is not a meaningful substitution for the cross-reference text.
