    <xsd:annotation>
      <xsd:documentation>
      OPTIONAL: Indicates how frequently the content at a particular URL is
      likely to change. The value "always" should be used to describe
      documents that change each time they are accessed. The value "never"
      should be used to describe archived URLs. Please note that web
      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.
