Bug in sub-grid documentation

This looks like a typo at http://docs.dhtmlx.com/doku.php?id=dhtmlxgrid:sub-grids

Later in XML the user will have the following code:

<rows>
<row id="some">
    <cell>my_grid.xml</cell><cell>Data </cell><cell>Data </cell>
<row>
</rows>

And in my_data.html there will be the following lines:

Shouldn’t it be the same file at both places?

mfyahya, thank you for your note and sorry for inconvenience.
We have corrected the mentioned documentation.
