Parameter configuration inheritance

In the preceding example, Magento\Backend\Block\Context is a descendant of Magento\Framework\View\Element\Context.

The first entry configures all instances of Magento\Framework\View\Element\Context as well as its children to pass in Magento\Core\Model\Url as $urlBuilder in their constructors.

The second entry overrides this and configures all instances of Magento\Backend\Block\Context to use Magento\Backend\Model\Url as the $urlBuilder instead.
