title: wordpress seo yoast change xml sitemap priority for taxonomy
body: <p>I'm using <strong>wordpress seo yoast plugin</strong> in to a web site.In the xml sitemap settings I enabled yoast plugin sitemap and it is working fine.In the admin panel there is the <strong>taxonomy</strong> named "stores". This is like categories. But i need to set it's priority <strong>from 20% to 60%</strong> in the store-sitemap.xml file.</p>
  
  <p><img src="https://i.stack.imgur.com/Cz2Co.png" alt="enter image description here"></p>
  
  <p>I added following filter and it is not worked and not displaying to set the <strong>priority</strong> when adding or editing the stores.</p>
  
  <pre><code>add_filter( 'wpseo_metabox_prio', 'move_yoast_metabox_down' );
  
  function move_yoast_metabox_down( $priority ) {
      return 'high';
  }
  </code></pre>
  
  <p>But this priority setting option can be view in the post types.
