semantics - ul 或 nav 用于 HTML 中的面包屑导航？

Question

Foundation前端框架提供2 ways of representing breadcrumbs在 HTML 中:

<ul class="breadcrumbs">
  <li><a href="#">Home</a></li>
  <li><a href="#">Features</a></li>
  <li class="unavailable"><a href="#">Gene Splicing</a></li>
  <li class="current"><a href="#">Cloning</a></li>
</ul>

以这种方式使用 nav和 a元素而不是 ul和 li :

<nav class="breadcrumbs">
  <a href="#">Home</a>
  <a href="#">Features</a>
  <a class="unavailable" href="#">Gene Splicing</a>
  <a class="current" href="#">Cloning</a>
</nav>

哪种方式在语义上更合适？

      <a href="index.html" title="Go to Home Page" itemprop="url">
        <span itemprop="title">Home</span>
      </a>
      <span>></span>
    </li>
    <li itemscope itemtype="http://data-vocabulary.org/Breadcrumb" class="category5">
      <a href="product.html" title="Product" itemprop="url">
        <span itemprop="title">product name</span>
      </a>
      <span>></span>
    </li>
    <li itemscope itemtype="http://data-vocabulary.org/Breadcrumb" class="category5">
      <a href=".finalproduct.html" title="final product" itemprop="url">
        <span itemprop="title">final product</span>
      </a>
      <span>></span>
    </li>
    <li class="category6"><strong>Final Product view</strong></li>
