<\body> The standard lists are defined in . The unnumbered lists environments are: <\explain|> The tag before each item depends on the nesting depth. <\explain|> Uses for the tag. <\explain|> Uses > for the tag. <\explain|> Uses > for the tag. The following environments can be used for producing numbered lists: <\explain|> The kind of number before each item depends on the nesting depth. <\explain|> Number the items by 1, 2, 3, <\explain|> Number the items by i, ii, iii, <\explain|> Number the items by I, II, III, <\explain|> Number the items by a), b), c), <\explain|> Number the items by A), B), C), The following environments can be used for descriptive lists: <\explain|> The environment for default descriptive lists (usually ). <\explain|> Align the left hand sides of the items in the list and put their descriptions shortly behind it. <\explain|> Similar to , but use a  to separate each item from its description. <\explain|> Align the left hand sides of the descriptions, while aligning the items to the right. <\explain|> Put the items and their descriptions on distinct lines. New items in a list are indicated through the tag or the tag in the case of descriptions. The tag takes no arguments and the tag one argument. When using the experimental package, these tags may take an optional body argument. In the future, all list items should become structured. By default, items in sublists are numbered in the same way as usual lists. Each list environment > admits a variant *> whose items are prefixed by the last item in the parent list. Of course, this feature can be used recursively. <\initial> <\collection>
