List item tokens must appear at the beginning of line as lists aren't allowed inside a preformatted box:
: foo -> <dl><dd> foo </dd></dl>
: foo -> <pre> : foo </pre>
However, if you put a table inside it, the list item token may appear indented:
:{| |foo |} -> <dl><dd><table><tbody><tr><td> foo </td></tr></tbody></table></dd></dl>
