Use of entities in the DataImportHandler config file

[Julio Castillo]

I'm trying to configure a document config file using the example
data-config.xml mentioned in the wiki.

One question I have is when to nest the entity tags/nodes in the xml file?
The proposed example has them nested as 
<document>
    <entity>
        <entity>
        </entity>
        <entity>
        </entity>
    </entity>
</document>

Why didn't the example had a flatter organization?
<document>
    <entity>
    </entity>
    <entity>
    </entity>
    ...
</document>
