      OPTIONAL: The priority of a particular URL relative to other pages

      on the same site. The value for this element is a number between

      0.0 and 1.0 where 0.0 identifies the lowest priority page(s).

      The default priority of a page is 0.5. Priority is used to select

      between pages on your site. Setting a priority of 1.0 for all URLs

      will not help you, as the relative priority of pages on your site

      is what will be considered.
