>If you read this, please send a message to the list saying whether you are
familiar with the use of [] for optionality and would guess that the square
brackets in
<value [type="NCName"]>string</value>
indicate that the attribute is optional.
Alternatively we could try to make it harder to miss the ? by adding
parentheses
<value (type="NCName")?>string</value>

You can also add annotation to denote this!
Putting the items inside the [in italics] is also a better visual hint .
