Are you talking about the XML format, or about particular C++ classes?

I can't imagine what meaning columns could have in notebooks or portals.
You would put a group inside a notebook and the group would have
columns, much like a GtkBox has many children, but a GtkWindow has only
one child.

I would welcome any correction to the DTD (which is currently just used
for documentation).

That's a great idea. I'd love to just use libgnomedb one day and remove
code from Glom.

Note that the flowing columned container widget is a separate problem in
itself. I'd love to see that in GTK+, but it really needs the
height-for-width "enhanced" layout system to be finally committed.
