I have a question regarding the TWE navbar: Within the documentation there is this snippit:

<ul
    class="list-style-none me-auto flex flex-col ps-0 lg:flex-row"
    data-twe-navbar-nav-ref>
    <li class="mb-4 lg:mb-0 lg:pe-2" data-twe-nav-item-ref>
      <!-- Dashboard link -->
      <a
        class="text-black/60 transition duration-200 hover:text-black/80 hover:ease-in-out focus:text-black/80 active:text-black/80 motion-reduce:transition-none dark:text-white/60 dark:hover:text-white/80 dark:focus:text-white/80 dark:active:text-white/80 lg:px-2"
        href="#"
        data-twe-nav-link-ref
        >Dashboard</a
      >

My question is, what the porpose of the data-twe-navbar-nav-ref, data-twe-nav-item-ref and data-twe-nav-link-ref attributes is. As far as I can see there is no documentation for them or did I miss that.
