How to give a package as a generic parameter in Ada?

I wonder what is the syntax to pass a package to a generic function. I've tried several ways without success.

for ex.:

generic
    with package <<SomeThing>> is <>;
    procedure forEach(g: in <<MyType>>);

OR

generic
    with package <<SomeThing>>;
    procedure forEach(g: in <<MyType>>);

OR

generic
    package <<SomeThing>>;
    procedure forEach(g: in <<MyType>>);

The package must be an instance of a generic package (otherwise the compiler would not know anything about the package). The syntax is:

generic
   with package Foo is new Bar (<>);
procedure Foreach (G : Foo.T);

See the Ada Wikibook and the examples at the end of the Reference Manual section on formal packages (ARM 12.7).
