list-type Type of List
Specifies what prefix character should precede each list item. Typically, the style
specifies the character type (a “simple” list for no character at all, a “bullet” list for bullet-style characters, or an “order” list for counting numbers or letters). The style may also name the character class
explicitly
(“alpha-lower” for a list numbered “a.”, “b.”, “c.”).
Usage/Remarks
Specifying Bullet Characters
If the @list-type specifies 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 what character to display. BITS 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 “order” for a numbered list whose prefix style is set at display time). |
Restriction | @list-type is an optional attribute; there is no default. |
