<p>Good point, but here is what it says about asterisks:</p>
<p><br>
</p>
<p></p>
<div>> Within productions, alternatives are separated by a vertical bar ('|'), and typically listed on separate <span style="font-size: 12pt;">lines. Optional symbols are enclosed in square brackets ('[' and ']'). Symbols may also be grouped </span><span style="font-size: 12pt;">using
parenthesis. The plus sign ('+') following a symbol or group of symbols indicates one or more </span><span style="font-size: 12pt;">repetitions; an asterisk ('*') indicates zero or more repetitions.</span></div>

<div>Btw the standard uses a modified EBNF to describe the productions. Thats explained in the first part of the standard. Everything cascades in the standard, so you really need to commit to reading the whole standard, not the Wikipedia article. Its a pain,
but Ive found it useful to do so. But then Ive been a computer geek for 48 years, and this type of stuff is what I get paid to do. So nitpicking is my job.<br>

<div dir="ltr">> The explanation is that, according to Wikipedia, an asterisk in the BNF stands for "0 or more times". So provided that there is not a mistake in the official standard document, shouldn't we support the above example?</div>
