<it> field

[elsdvlee]

Should the <it> field result in a logical iteration that you can further reference? What would the <it> contain in case of CSV of relational table? What about a joined logicalView? How would the <it> look like then? Is the <it> field still needed?

During the meeting it was stated that one could refer to it via an expression. Would the iteration have a reference to a subdocument to the whole document (in XML, for example), or create a new document for each iteration. In the case of the former, one could grab the parent(s) of a sub document. This could thus potentially be used to manipulate the iterator. In other words, the behavior needs to be clarified.

@pmaria What did you have in mind? Last useful note from the TF meetings on this topic:

<it> is about accessing the raw value of an iteration and doesn't need to be referenceable basic need: to define what it is that the value of fields provides
