The WG has entered this as an issue.

Personally I agree with you, but I wonder whether we need a bit more
than just the existing DTD alternatives, if that is what you were
suggesting.

For mapping arrays with a fixed number of elements into XML, minOccur
and maxOccur are in any case not what is needed - so maybe something
more like lowerBound and upperBound on indexing into ordered collections
as a way of constraining + more strongly?  Even lowerBound is a bit
generous towards languages that support it or use 0-indexing, and if we
didn't need that we could just have Occurs.

Regards,
