This will output a very basic XML document with one XML element:

Dealing with Component Configuration
The chances are that a component that we are building is going to need some
configuration options. Every component can store default parameters about itself.
A relationship exists between menu items and the component configuration. The
configuration edited from within the component defines the default configuration.
When we create a new menu item, we can modify the component configuration
specifically for the menu item. This enables us to override the default configuration
on a per-menu-item basis.
To define component parameters we must create an XML metadata file, called
config.
