Yes, we are doing that, but unfortunately the code isn't polished enough to
be public.
We have a 'download' link on top of our reports that allows you to download
the data that you see (in CSV, for example).

We have a special page for that that gets initialized with an ITableModel
before it is rendered. The page generates CSV (or XML in your case) based on
the data that the ITableModel gives it. The content type is selected by
modifying getResponseWriter().

If you are using contrib:Table with the source and columns parameters, you
can do the following to get an ITableModel:

Table tbl = (Table) getComponent("table"); // replace this with your
component name
ITableModel model = tbl.getTableModel();

You can do that before transferring control to the page described above and
pass that model to it.

Hope this helps,
