Rendering tree using CSV format - reg

Evaluating the dhtmltree for one of our product. I am able to render the tree using XML data. Since we have large number of tree nodes even at the first level, I am trying to load using CSV format.In the help document, it is shown to provide only 3 arguments(id,parentid, label) per tree node.

Is it not possible to provide additional information like (Has Child, custom node Image) as we are giving in xml format.
In our product, the input data for tree construction is coming from serverside. If it is CSV format, tree construction will be simple compared to other format.

Thanks,
Sivakumar
