how GitHub cleans.\n * If any top-level key is missing in the given schema, the corresponding\n * value of the default schema is used.\n *\n * To extend the standard schema with a few changes, clone `defaultSchema`\n * like so:\n *\n * ```js\n * import deepmerge from 'deepmerge'\n * import {h} from 'hastscript'\n * import {defaultSchema, sanitize} from 'hast-util-sanitize'\n *\n * // This allows `className` on all elements.\n * const schema = deepmerge(defaultSchema, {attributes: {'*': ['className']}})\n *\n * const tree = sanitize(h('div', {className: ['foo']}), schema)\n *\n * // `tree` still has `className`.\n * console.log(tree)\n * // {\n * // type: 'element',\n * // tagName: 'div',\n * // properties: {className: ['foo']},\n * // children: []\n * // }\n * ```\n * @property {boolean | null | undefined} [allowComments=false]\n * Whether to allow comment nodes (default: `false`).\n *\n * For example:\n *\n * ```js\n * allowComments: true\n * ```\n * @property {boolean | null | undefined} [allowDoctypes=false]\n * Whether to allow doctype nodes (default: `false`).\n *\n * For example:\n *\n * ```js\n * allowDoctypes: true\n * ```\n * @property {Record> | null | undefined} [ancestors]\n * Map of tag names to a list of tag names which are required ancestors\n * (default: `defaultSchema.ancestors`).\n *\n * Elements with these tag names will be ignored if they occur outside of one\n * of their allowed parents.\n *\n * For example:\n *\n * ```js\n * ancestors: {\n * tbody: ['table'],\n * // …\n * tr: ['table']\n * }\n * ```\n * @property {Record> | null | undefined} [attributes]\n * Map of tag names to allowed property names (default:\n * `defaultSchema.attributes`).\n *\n * The special key `'*'` as a tag name defines property names allowed on all\n * elements.\n *\n * The special value `'data*'` as a property name can be used to allow all\n * `data` properties.\n *\n * For example:\n *\n * ```js\n * attributes: {\n * 'ariaDescribedBy', 'ariaLabel', 'ariaLabelledBy', …, 'href'\n * // …\n * '*': [\n * 'abbr',\n * 'accept',\n * 'acceptCharset',\n * // …\n * 'vAlign',\n * 'value',\n * 'width'\n * ]\n * }\n * ```\n *\n * Instead of a single string in the array, which allows any property value\n * for the field, you can use an array to allow several values.\n * For example, `input: ['type']` allows `type` set to any value on `input`s.\n * But `input: [['type', 'checkbox', 'radio']]` allows `type` when set to\n * `'checkbox'` or `'radio'`.\n *\n * You can use regexes, so for example `span: [['className', /^hljs-/]]`\n * allows any class that starts with `hljs-` on `span`s.\n *\n * When comma- or space-separated values are used (such as `className`), each\n * value in is checked individually.\n * For example, to allow certain classes on `span`s for syntax highlighting,\n * use `span: [['className', 'number', 'operator', 'token']]`.\n * This will allow `'number'`, `'operator'`, and `'token'` classes, but drop\n * others.\n * @property {Array | null | undefined} [clobber]\n * List of property names that clobber (default: `defaultSchema.clobber`).\n *\n * For example:\n *\n * ```js\n * clobber: ['ariaDescribedBy', 'ariaLabelledBy', 'id', 'name']\n * ```\n * @property {string | null | undefined} [clobberPrefix]\n * Prefix to use before clobbering properties (default:\n * `defaultSchema.clobberPrefix`).\n *\n * For example:\n *\n * ```js\n * clobberPrefix: 'user-content-'\n * ```\n * @property {Record | null | undefined> | null | undefined} [protocols]\n * Map of *property names* to allowed protocols (default:\n * `defaultSchema.protocols`).\n *\n * This defines URLs that are always allowed to have local URLs (relative to\n * the current website, such as `this`, `#this`, `/this`, or `?this`), and\n * only allowed to have remote URLs (such as `https://example.com`) if they\n * use a known protocol.\n *\n * For example:\n *\n * ```js\n * protocols: {\n * cite: ['http', 'https'],\n * // …\n * src: ['http', 'https']\n * }\n * ```\n * @property {Record> | null | undefined} [required]\n * Map of tag names to required property names with a default value\n * (default: `defaultSchema.required`).\n *\n * This defines properties that must be set.\n * If a field does not exist (after the element was made safe), these will be\n * added with the given value.\n *\n * For example:\n *\n * ```js\n * required: {\n * input: {disabled: true, type: 'checkbox'}\n * }\n * ```\n *\n * > 👉 **Note**: properties are first checked based on `schema.attributes`,\n * > then on `schema.required`.\n * > That means properties could be removed by `attributes` and then added\n * > again with `required`.\n * @property {Array | null | undefined} [strip]\n * List of tag names to strip from the tree (default: `defaultSchema.strip`).\n *\n * By default, unsafe elements (those not in `schema.tagNames`) are replaced\n * by what they contain.\n * This option can drop
