Add attributes like "data-" to TDs -- How-to

I needed to have attributes added to the TD in my dataTable.
As I thought to use RowCallback would be to late to add those attributes and also because all is in the aoColumns, I mean the descriptions of the cells, I thought of of solution:

- added a field "aAttrs" in the column description which is the attributes I wish to add
- to change _fnCreateTr to take into account those news attributes.

So, to add an attribute like data-type="text", I simply put in my column descriptor a aAttrs:{ 'data-type': 'text' }

and I modified the function _fnCreateTr around line 1122 like:

nTd = document.createElement( oCol.sCellType );

/* ADD ATTRIBUTES IF ASKED */
if ( oCol.aAttrs && typeof oCol.aAttrs == 'object' ) {
	for ( var at in oCol.aAttrs )
	{
		nTd.setAttribute(at,oCol.aAttrs[at]);
	}
}
			
/* Render if needed - if bUseRendered is true then we already have the rendered
 * value in the data source - so can just use that
 */
nTd.innerHTML = (typeof oCol.fnRender === 'function' && (!oCol.bUseRendered || oCol.mData === null)) ?
	_fnRender( oSettings, iRow, i ) :
	_fnGetCellData( oSettings, iRow, i, 'display' );

What do you think of this ?
Let's say I would be extremely pleased if this could be validated in the next version ;)

Thanks for your attention.
