So, first off, names are not allowed to have brackets internally so that
a variety of other features will work (overloading access, primarily).

That said, you *can* force brackets to appear in the output in a couple
of different ways.

* If you want brackets for allowing multiple values to be captured --
i.e., a name like 'foo[]' -- turn on the isArray property:

$element->setIsArray(true); // or pass a true value to the
// "isArray" key during
// instantiation

* If you want the value to be a key in another value, e.g.,
"bar[foo]", then you need to tell the element it belongs to another
value:

$element->setBelongsTo('bar'); // or pass the value to the
// 'belongsTo' key during
// instantiation

* If you use sub forms, array notation happens by default; all
elements "belongTo" the name of the sub form
