 Rich,
 your first suggestion is a good one, I think. This part of the
text was copied from the current editors' copy of the spec.
 To the second, for example: offset "1 1 1" is not as good as
position in the case of an array of size "2 * *" with four
members, because the members can be on positions [1 1 1], [1 1
2], [1 1 3], [1 1 4] or [1 1 1], [1 1 2], [1 2 1], [1 2 2] or any
other combinations.
 Even if there is only one asterisk, for example size="2 * 2",
it's easy to deserialize the array when we know the exact number
of the members and no explicit position interferes.
 To summarize - an asterisk in any position other than the first
brings difficulties during deserialization unless all members
specify their exact position, which is exactly what the text
requires. 8-)
 Take care,

                   Jacek Kopecky
