Mike McGann commented on DAFFODIL-2364:
---------------------------------------
The validation check happens here:
https://github.com/apache/daffodil/blob/dede0cf7dfaa3a7e67af5dabc7389192eb92c4d5/daffodil-runtime1/src/main/scala/org/apache/daffodil/runtime1/processors/parsers/SequenceChildBases.scala#L518-L534
It appears to be using a counter of the current array index and using that for
the count. But that number includes empty elements even if they are removed in
the final infoset. I'm not sure how the code should be validating the infoset
here and could use some assistance.
