[jira] [Created] (DAFFODIL-2979) optional element in expression should not require indexing

---------------------------------------

             Summary: optional element in expression should not require indexing
                 Key: DAFFODIL-2979
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2979
             Project: Daffodil
          Issue Type: Bug
          Components: Front End
    Affects Versions: 3.10.0
            Reporter: Mike Beckerle


 

Suppose 'bar' is an optional element, i.e., minOccurs 0, maxOccurs 1 and 
dfdl:occursCountKind is not 'parsed' (because that would make it an array).

 

Then expressions like:

```

    foo/bar/baz

```

should *not* require indexing a child of the bar element. I.e., this should 
*not* be required but was reported that it is required:

```

   foo/bar[1]/baz

```

The indexing should only be _required_ for arrays.
