In a lot of the examples I see online for repeating record based data, mainly when converting flat file formats to XML, I notice that people often insert an extra node between the repeating record node and the record fields.
The screenshot of Example 1 linked below illustrates this...

The screenshot of Example 2 linked below is essentially the same, without the additional node under the record node...

I'm curious why people add the extra node. Does it make mapping easier in certain situations? I see it done quite a lot.
