> Recent emails on users@daffodil.apache.org have shown that when parsing, if an array element results in no-forward-progress that we don't terminate the array, but rather the failure occurs outside of the scope of the speculative parse of the array element; hence, the entire PoU containing the array fails.
> This is wrong. The failure should occurs within the scope of speculation for the next array element. A forward progress failure should terminate the array, preserving any previously successfully parsed elements, not fail the entire thing.
