<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">It's not necessarily solvable in schema if the intention is to relax order, because I think the cardinalities all end up matching in the end, and you're stuck enforcing it in code.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In general the parsers already _should _re-enforce the 0/1/Many constraint and they are absolutely safe from mixing things up (and there are tests for that). But this case is to go over every flattened sequence where there is an expectation of just 1 and make sure that the parsers do check. </p>
