A number of tokens are described as being a sequence of "zero or more" of something. Here are a few examples:

--
A WebVTT cue settings list consist of a sequence of zero or more WebVTT cue settings in any order, separated from each other by one or more U+0020 SPACE characters
--
A WebVTT cue setting name and a WebVTT cue setting value each consist of any sequence of zero or more characters other than U+000A LINE FEED (LF) characters and U+000D CARRIAGE RETURN (CR) characters except that the entire resulting string must not contain the substring "-->" (U+002D HYPHEN-MINUS, U+002D HYPHEN-MINUS, U+003E GREATER-THAN SIGN).
--

A zero-length string seems problematic, since each space character can be considered to separate one such zero-length entity. Should these be reconsidered to be "one or more..."?
