Whoops, forgot about the nesting.

Nested packages can be modelled directly by nesting the categories. Again, the
classes can be assigned directly to the component.

The component usually corresponds to the source file with the implementation,
and does not indicate the nesting directly. Rather, the nesting is indicated
in the class diagrams.

If you really want to show the nesting in component diagram (especially for
child packages where they are in different files), create a subsystem for each
package, nested accordingly. Also create a corresponding component to describe
what types (i.e. classes) are in each package. E.g for these packages:

  package Root is
    type Root_Class is ...
  end Root;

  package Root.Child is
     type Child_Class is ...
  end Root.Child;

Create these components and subsystems:

  Root\
    Root.ada <-- Root_Class is assigned to this component
    Child\
      Root_Child.ada <-- Child_Class is assigned to this component

The logical view would have these categories and classes:

  Root\
    Root_Class
    Child\
      Child_Class
