* are attached to elements using the #attached property. The #attached property

* 'js', 'css', and 'library' are types that get special handling. For any
* other kind of attached data, the array key must be the full name of the
* callback function and each value an array of arguments. For example:
* The available keys are:
* - 'library' (asset libraries)
* - 'drupalSettings' (JavaScript settings)
* - 'feed' (RSS feeds)
* - 'html_head' (tags in HTML <head>)
* - 'html_head_link' (<link> tags in HTML <head>)
