 * @remarks
 *
 * The schema is the most important part of the remirror editor. This is the
 * extension responsible for creating it, injecting extra attributes and
 * managing the plugin which is responsible for making sure dynamically created
 * attributes are updated.
 *
 * In order to add extra attributes the following would work.
 *
 * ```ts
 * import { RemirrorManager } from 'remirror';
 * import uuid from 'uuid';
 * import hash from 'made-up-hasher';
 *
 * const manager = RemirrorManager.create([], {
 *   extraAttributes: [
 *     {
 *       identifiers: 'nodes',
 *       attributes: {
 *         awesome: {
 *           default: 'awesome',
 *           parseDOM: (domNode) => domNode.getAttribute('data-awesome'),
 *           toDOM: (attrs) => ([ 'data-awesome', attrs.awesome ])

 *     { identifiers: ['bold'], attributes: { hash: (mark) => hash(JSON.stringify(mark.attrs)) } },
 *   ],
 * })
 * ```
 *
 * It is an array of identifiers and attributes. Setting the default to a
 * function allows you to set up a dynamic attribute which is updated with the
 * synchronous function that you provide to it.
