`html` nodes and can be embedded in hast\n * as semistandard `raw` nodes.\n * Most plugins ignore `raw` nodes but two notable ones don’t:\n *\n * * `rehype-stringify` also has an option `allowDangerousHtml` which will\n * output the raw HTML.\n * This is typically discouraged as noted by the option name but is useful if\n * you completely trust authors\n * * `rehype-raw` can handle the raw embedded HTML strings by parsing them\n * into standard hast nodes (`element`, `text`, etc);\n * this is a heavy task as it needs a full HTML parser,\n * but it is the only way to support untrusted content\n *\n * ###### Footnotes\n *\n * Many options supported here relate to footnotes.\n * Footnotes are not specified by CommonMark,\n * which we follow by default.\n * They are supported by GitHub,\n * so footnotes can be enabled in markdown with `remark-gfm`.\n *\n * The options `footnoteBackLabel` and `footnoteLabel` define natural language\n * that explains footnotes,\n * which is hidden for sighted users but shown to assistive technology.\n * When your page is not in English,\n * you must define translated values.\n *\n * Back references use ARIA attributes,\n * but the section label itself uses a heading that is hidden with an\n * `sr-only` class.\n * To show it to sighted users,\n * define different attributes in `footnoteLabelProperties`.\n *\n * ###### Clobbering\n *\n * Footnotes introduces a problem,\n * as it links footnote calls to footnote definitions on the page through `id`\n * attributes generated from user content,\n * which results in DOM clobbering.\n *\n * DOM clobbering is this:\n *\n * ```html\n * \n * \n * ```\n *\n * Elements by their ID are made available by browsers on the `window` object,\n * which is a security risk.\n * Using a prefix solves this problem.\n *\n * More information on how to handle clobbering and the prefix is explained in\n * *Example: headings (DOM clobbering)* in `rehype-sanitize`.\n *\n * ######

doesn’t have `data.hName`, `data.hProperties`, or `data.hChildren`,\n * see later),\n * create a hast `text` node\n * * otherwise,\n * create a `` element (which could be changed with `data.hName`),\n
