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

Per review comment from Brandon Sloane:

 
{quote}{ . } and \{ .[1] } are the same thing when the current node is an element, aren't they? I don't think "." is supposed to elevate you to the array containing the current element. I tested this here: [https://www.freeformatter.com/xpath-tester.html] with the xml:
{{<foo> <a>1</a> <a>2</a> <a>3</a> </foo> }}
where the expression {{foo/a[2]/.[1]}} resolved to 2
{quote}
This issue may have been discussed in DFDL workgroup email archives in the past. Must search there and/or get clarification about the behavior of .[i].

> I believe when an element is an array, that .[i] should be meaningful.
> It appears that the DPath compiler is creating an implementation that just gets the value of the current element ignoring the indexing.
