 If the file returns a lambda function, that function gets called every time the component is invoked. If the
 file returns a text, that text gets returned every time the component is invoked.
 
-`$id_override` is an optional parameter intended to override the component's HTML element id.
-As a rule, components should encapsulate themselves with an outer HTML element, like this:
-`<div <?= ap($prop) ?> class="menu-bar">...</div>`. The call to `ap($prop)` generates an `id`
-attribute automatically. The value of this `id` can be explicitly set by using the `$id_override`
-parameter. This is useful when the elements later needs to be reloaded or regenerated dynamically.
-
 `$prop` is an optional parameter to communicate further parameters to the component, and this
 corresponds to the `$prop` parameter being passed to a component's lambda function.
