Do not view them as attributes, they are simply parameters that need to be
passed in and they can be different types such as ints, strings, boolean are
other objects, attribute object neatly fits that bill to pass parameters of
different types. I can simply extend attribute and call it parameter and it
would give me the same functionality.
