     * They are used to create the final description presented in the suggestion view to the user.
     *
     * Note that one suggestion may include multiple changes.
     *
     * Most cases are simple and include just one description item:
     *
     *  ```ts
     * [
     *		{ type: 'insertion', content: '*Insert:* "Foo"' }
     * ]
     *	```
     *
     * This description item represents a suggestion for inserting the "Foo" text. The `type` property describes the performed action
     * while the `content` property contains additional information about the action and is optional.
     *
     * A more complex example is presented below:
     *
     * ```ts
     * [
     *		{ type: 'insertion', content: '*Insert:* 2 paragraphs' },
     *		{ type: 'insertion', content: '*Insert:* image' },
     *		{ type: 'replace', content: '*Replace:* "Foo" *with* "Bar"' }
     * ]
     * ```
     *
     * In this example, there are three description instances (or lines). Two new (empty) paragraphs were added,
     * an image was added and then "Foo" text was replaced by "Bar". The above structure could be rendered as:
     *
     *  ```html
     *	<p><strong>Insert:</strong> 2 paragraphs</p>
     *	<p><strong>Insert:</strong> image</p>
     *	<p><strong>Replace:</strong> "Foo" <strong>with</strong> "Bar"</p>
     *	```
