Yes, I don't know the details but DataControls behave differently according
to the underlying field type. The thing with the primary index is that you
should (or can?) not change it. The bold font is most likely an aesthetic
thing. So far the reason. (You can also have a look at the source code[0].)

If you can influence the DataControl's self-setup, or if it can be
implemented, is something Benoit has to say.

    and the accompanying DataField.class are particularly interesting here.
    Both are relatively easy to comprehend for such an advanced component.
