It would seem natural that the custom widget provided a `style'
attribute, along the lines of
    <div style="border: 1px solid black;"">...</div>
where the widget could specify its mimicking settings, be it in the
syntax sketched above or otherwise.

This functionality is not yet available in the CSS engine, I've been
thinking of g_object_[gs]et_data() with a key "gce-style" or
something, for test-driving this. (Probably compile-time opt-in in the
CSS engine). Gtk3's widgets could eventually support this natively, if
CSS support went into gtk proper.
