      documents that change each time they are accessed. The value "never"

      crawlers may not necessarily crawl pages marked "always" more often.
      Consider this element as a friendly suggestion and not a command.

<xsd:element name="priority">
  <xsd:annotation>
    <xsd:documentation>
      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.
