 * Generally, if a value is a string it will be set as the text for an element
 * and if an object it will recurse on the properties. To support values that
 * are an array,
 * {@linkcode https://developer.mozilla.org/en-US/docs/Web/API/HTMLTemplateElement | HTMLTemplateElement}s
 * are used. Each item in the array looks for a template with an attribute
 * `data-type` that matches the type. Strings look for a type of `Text`.
 *
 * @param data - The micro data to apply.
 * @param element - The root of the HTML element tree.
 * @param options - Optional options for applying data.
 *
 * @see {@link https://html.spec.whatwg.org/multipage/microdata.html}
