+/**
+ * Element wrapper for the [marked](https://github.com/chjj/marked) library.
+ *
+ * `<marked-element>` accepts Markdown source and renders it to a child
+ * element with the class `markdown-html`. This child element can be styled
+ * as you would a normal DOM element. If you do not provide a child element
+ * with the `markdown-html` class, the Markdown source will still be rendered,
+ * but to a shadow DOM child that cannot be styled.
+ *
+ *
+ * ### Markdown Content
+ *
+ * The Markdown source can be specified several ways:
+ *
+ * #### Use the `markdown` attribute to bind markdown
+ *
+ *     <marked-element markdown="`Markdown` is _awesome_!">
+ *       <div slot="markdown-html"></div>
+ *     </marked-element>
+ *
+ * #### Use `<script type="text/markdown">` element child to inline markdown
+ *
+ *     <marked-element>
+ *       <div slot="markdown-html"></div>
+ *       <script type="text/markdown">
+ *         Check out my markdown!
+ *
+ *         We can even embed elements without fear of the HTML parser mucking up their
+ *         textual representation:
+ *
+ *         ```html
+ *         <awesome-sauce>
+ *           <div>Oops, I'm about to forget to close this div.
+ *         </awesome-sauce>
+ *         ```
+ *       </script>
+ *     </marked-element>
+ *
+ * #### Use `<script type="text/markdown" src="URL">` element child to specify remote markdown
+ *
+ *     <marked-element>
+ *       <div slot="markdown-html"></div>
+ *       <script type="text/markdown" src="../guidelines.md"></script>
+ *     </marked-element>
+ *
+ * Note that the `<script type="text/markdown">` approach is *static*. Changes to
+ * the script content will *not* update the rendered markdown!
+ *
+ * Though, you can data bind to the `src` attribute to change the markdown.
+ *
+ * ```html
+ * <marked-element>
+ *   <div slot="markdown-html"></div>
+ *   <script type="text/markdown" src$="[[source]]"></script>
+ * </marked-element>
+ * ...
+ * <script>
+ *   ...
+ *   this.source = '../guidelines.md';
+ * </script>
+ * ```
+ *
+ * ### Styling
+ * If you are using a child with the `markdown-html` class, you can style it
+ * as you would a regular DOM element:
+ *
+ *     [slot="markdown-html"] p {
+ *       color: red;
+ *     }
+ *
+ *     [slot="markdown-html"] td:first-child {
+ *       padding-left: 24px;
+ *     }
