Hello!

Which of the two menu layout options is the only correct one?

div id="menu">
   <nav itemscope itemtype="http://schema.org/SiteNavigationElement">
      <a href="главная.php" itemprop="url"><span itemprop="name">Главная</span></a>
      <a href="продукция.php" itemprop="url"><span itemprop="name">Продукция</span></a>
      <a href="покупателям.php" itemprop="url"><span itemprop="name">Покупателям</span></a>
   </nav>
</div>

...or:

<div id="menu">
   <nav itemscope itemtype="http://schema.org/SiteNavigationElement">
      <a href="главная.php" itemprop="url name">Главная</a>
      <a href="продукция.php" itemprop="url name">Продукция</a>
      <a href="покупателям.php" itemprop="url name">Покупателям</a>
