Modules Best Practices

Hello,

After discussing names on the Gtk2-perl mailing list I've registered a 
namespace with CPAN, Gtk2::Ex::MindMapView. This is a module that draws 
a mindmap, or outline, on a Gnome2::Canvas. Actually, it consists of 13 
modules and the number of modules is anticipated to grow. I anticipate 
that all modules will be under the currently registered namespace. For 
example, one of the modules will have the name: 
Gtk2::Ex::MindMapView::Layout::Balanced, another will have the name 
Gtk2::Ex::MindMapView::Item, and the main module is Gtk2::Ex::MindMapView.

I am preparing to upload the first version of this module, but before 
doing that I would like to know what the "best practice" is for 
registering modules with CPAN. Should I register all modules in a given 
namespace with CPAN?
