<listitem> (List Item) Description .email comment.
Description
This element holds one item of a list. This include lists with no prefix, symbol prefixes and numbered prefixes, but not definition lists (where each item is actually two components: a term and a definition).
   simple item one
 
   simple item two
 
   simple item three
   -  itemized item one
 
   -  itemized item two
 
   -  itemized item three
   1)  sequenced item one
 
   2)  sequenced item two
 
   3)  sequenced item three
Although complete simple lists can be given an indentation value, it is also possible to give separate indentation values to list items in any of the list types (except definition lists). However, it is also possible to embed one list within another, and when this happens the inner list items should be automatically indented appropriately. Therefore, indentation values should only be used for simple list items (and entire simple lists).
Parent Elements
The elements listed below may directly contain this element. They are "parent" elements. Elements in referenced groups are included, up to two levels of group nesting.
