/**
 * Gets an sets of annotated HTML fragments for rendering by ve.ce.ContentBranchNode.
 *
 * An HTML fragment can be:
 * - an HTML string
 * - a jQuery object
 * - an array with an HTML string or jQuery object at index 0 and a ve.AnnotationSet at index 1,
 *   i.e. ['htmlstring', ve.AnnotationSet] or [$jQueryObj, ve.AnnotationSet]
 *
 * The default implementation should be fine in most cases. A subclass only needs to override this
 * if the annotations aren't necessarily the same across the entire node (like in ve.ce.TextNode).
 *
 * @method
 * @returns {Array} Array of HTML fragments, i.e
 *                   [ string | jQuery | [string|jQuery, ve.AnnotationSet] ]
