   *
   * **Note:** ASCII-incompatible encodings are those that don't map the 8-bit code points `0x20` to `0x7E` to the `0x0020` to `0x007E` Unicode code points)

   * *   Authors should not use `UTF-32` because not all HTML5 encoding algorithms can distinguish it from `UTF-16`.
   *
   * **Notes:**
   *
   * *   The declared character encoding must match the one the page was saved with to avoid garbled characters and security holes.
   * *   The [`<meta>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta "The HTML <meta> element represents metadata that cannot be represented by other HTML meta-related elements, like <base>, <link>, <script>, <style> or <title>.") element declaring the encoding must be inside the [`<head>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/head "The HTML <head> element provides general information (metadata) about the document, including its title and links to its scripts and style sheets.") element and **within the first 1024 bytes** of the HTML as some browsers only look at those bytes before choosing an encoding.
   * *   This [`<meta>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta "The HTML <meta> element represents metadata that cannot be represented by other HTML meta-related elements, like <base>, <link>, <script>, <style> or <title>.") element is only one part of the [algorithm to determine a page's character set](https://www.whatwg.org/specs/web-apps/current-work/multipage/parsing.html#encoding-sniffing-algorithm "Algorithm charset page").

   *
   *     **Notes:**
   *
   *     *   Some browsers support the deprecated values of `always`, `default`, and `never` for referrer.
   *     *   Dynamically inserting `<meta name="referrer">` (with [`document.write`](https://developer.mozilla.org/en-US/docs/Web/API/Document/write) or [`appendChild`](https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild)) makes the referrer behaviour unpredictable.

   *
   *     *   Only cooperative robots follow these rules. Do not expect to prevent e-mail harvesters with them.
   *     *   The robot still needs to access the page in order to read these rules. To prevent bandwidth consumption, use a _[robots.txt](https://developer.mozilla.org/en-US/docs/Glossary/robots.txt "robots.txt: Robots.txt is a file which is usually placed in the root of any website. It decides whether crawlers are permitted or forbidden access to the web site.")_ file.
   *     *   If you want to remove a page, `noindex` will work, but only after the robot visits the page again. Ensure that the `robots.txt` file is not preventing revisits.
   *     *   Some values are mutually exclusive, like `index` and `noindex`, or `follow` and `nofollow`. In these cases the robot's behaviour is undefined and may vary between them.
   *     *   Some crawler robots, like Google, Yahoo and Bing, support the same values for the HTTP header `X-Robots-Tag`; this allows non-HTML documents like images to use these rules.
   *
   * *   `slurp`, is a synonym of `robots`, but only for Slurp - the crawler for Yahoo Search.
   * *   `viewport`, which gives hints about the size of the initial size of the [viewport](https://developer.mozilla.org/en-US/docs/Glossary/viewport "viewport: A viewport represents a polygonal (normally rectangular) area in computer graphics that is currently being viewed. In web browser terms, it refers to the part of the document you're viewing which is currently visible in its window (or the screen, if the document is being viewed in full screen mode).

   * This attribute indicates the type of script represented. The value of this attribute will be in one of the following categories:
   *
   * *   **Omitted or a JavaScript MIME type:** For HTML5-compliant browsers this indicates the script is JavaScript. HTML5 specification urges authors to omit the attribute rather than provide a redundant MIME type. In earlier browsers, this identified the scripting language of the embedded or imported (via the `src` attribute) code. JavaScript MIME types are [listed in the specification](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types#JavaScript_types).
   * *   **`module`:** For HTML5-compliant browsers the code is treated as a JavaScript module. The processing of the script contents is not affected by the `charset` and `defer` attributes. For information on using `module`, see [ES6 in Depth: Modules](https://hacks.mozilla.org/2015/08/es6-in-depth-modules/). Code may behave differently when the `module` keyword is used.
   * *   **Any other value:** The embedded content is treated as a data block which won't be processed by the browser. Developers must use a valid MIME type that is not a JavaScript MIME type to denote data blocks. The `src` attribute will be ignored.
   *
   * **Note:** in Firefox you could specify the version of JavaScript contained in a `<script>` element by including a non-standard `version` parameter inside the `type` attribute — for example `type="text/javascript;version=1.8"`. This has been removed in Firefox 59 (see [bug 1428745](https://bugzilla.mozilla.org/show_bug.cgi?id=1428745 "FIXED: Remove support for version parameter from script loader")).
