1. Build a standard sub form with the required elements
2. Instantiate, and call setName() on it with a unique name
3. Attach to the master form
4. Repeat from 1 as necessary.

When they are attached as sub forms, you simply validate the form. Since
each sub form will have a unique name, you don't have to worry about
anything; it should "just work."(tm)

Start with a common identifier 'address', and attach the sub forms in a
loop, appending an integer identifier:
for ($i = 1; $i < 11; ++$i) {
$subForm = new My_Form_Address();
$form->addSubForm($subForm, $address . $i);
}
