list-type Type of List
Specifies what prefix character should precede each list item. For example, the list
type
may suggest the character style (“simple”, “order” or
“bullet”), or the list type may name the character explicitly
(e.g., “lower-alpha” for a list numbered “a.”, “b.”, “c.”).
Usage/Remarks
Specifying Bullet Characters
If the @list-type names a bulleted style (“@list-type="bullet"”), the @style-detail attribute may be used to name the preferred prefix character such as “dash”, “hollow-bullet”, or “square”. If no @style-detail is given, the processing system will choose the bullet character. The NISO STS standard
neither establishes nor suggests values for the Styling Detail attribute.
An explicit <label> that is part of a list item always takes precedence over the Type of List or Styling Detail attributes.
Prefix Words
Whether a list-item prefix character is established by a named @list-type, or through the use of @style-detail for a bulleted list, the prefix character may be enhanced by a prefix word, named
in the @prefix-word attribute.
A prefix word is in addition to, and typically preceding, any prefix characters (numbers,
bullets). For example, a list type of “order” and a prefix word of “Step” would produce: “Step1. aaaa”, “Step2. bbbb”, “Step3. cccc”, etc. Note that typically, no white space follows the inserted word, i.e., “Step” rather than “Step ”.
The standard exception to this order is the display order for a bulleted list, in
which the prefix character would precede the prefix word—“• Step” rather than “ Step•”.
OPTIONAL on elements: <def-list>, <list>
Value | Meaning |
---|---|
A word | A word that either (1) specifies the character to be used for the list-item prefix (for example, the word “bullet” for a list with bulleted items) or (2) describes the appearance or format of the list items (for example, the word “simple” for a list that has no prefix character before each list item or the word “ordered” for a numbered list whose numbering style is set at display time). |
Restriction | This is an optional attribute; there is no default. |
Suggested usage
Although this attribute is designed to accept any text as its value, the following
are suggested
list types, which name the prefix character for each item in the list. Lists with
non-sequential prefix characters (that are not continued from another list) will always
need to encode the prefix character using the <label> element.
order
|
Ordered list. Prefix character may display as an arabic number, roman numeral, or
letter, depending on
style. List does not suggest the prefix character.
|
---|---|
bullet
|
Bulleted or unordered list. Prefix character may be a bullet, dash, asterisk, square
bullet, or other
symbol. This list is what HTML and Doc-Book mean by an “unordered” list. (Note: To
specify a particular prefix character, use the @style-detail attribute in addition to the value “bullet”. See the section above “Specifying Bullet Characters”.)
|
alpha-lower
|
Ordered list. Prefix character is a lowercase alphabetical character.
|
alpha-upper
|
Ordered list. Prefix character is an uppercase alphabetical
character.
|
arabic
|
Ordered list. Prefix character is an arabic numeral.
|
roman-lower
|
Ordered list. Prefix character is a lowercase roman numeral.
|
roman-upper
|
Ordered list. Prefix character is an uppercase roman numeral.
|
simple
|
Simple or plain list (No prefix character before each item)
