prefix-word  Prefix Word (For a List Item)

Word or phrase to be added to the beginning of each item in a list (for example, “Step”, “Procedure”).

Usage/Remarks

Display of Prefix Words with Prefix Characters: Any prefix word is in addition to, and typically precedes, any prefix character (number, bullet, dash). For example, a list type of “order” (which asks for an Arabic number) 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., “Step2” rather than “Step 2”.
The standard exception to this display order is the bulleted list, in which the prefix character (bullet, dash, etc.) would precede the prefix word—“• Step” rather than “Step•”.
OPTIONAL on elements: <def-list>, <list>
Value Meaning
Text, numbers, or special characters The prefix word to be used for the list; for example, the word “Step” might be used to display a list numbered “Step1.”, “Step2.”, “Step3.”, etc.
