DefaultPageXML in custom Route

What type of XML can I put in the DefaultPageXML param of a custom Route?  I exported a page, but not sure if it needs the entire export or only what is in the ContentFragmentPage node?

controller.AddPage(page.PageKey, page.RoutePath, null, null, page.PageKey, new PageDefinitionOptions() {DefaultPageXml ParseContext = ParseCMSPageContext });

 <contentFragmentPage pageName="family-services" isCustom="false" layout="Content" themeType="0c647246-6735-42f9-875d-c8b991fe739b" lastModified="2019-05-30 05:50:02Z">
      <regions>
        <region regionName="Content">
          <contentFragments>
            <contentFragment type="Telligent.Evolution.ScriptedContentFragments.ScriptedContentFragment, Telligent.Evolution.Platform::50c816b46c7647d5a7cea85b3f47d4d6" showHeader="True" cssClassAddition="top-border with-spacing with-header responsive-1" isLocked="False" configuration="title=Family%20Services&html=%3Cp%3EFamily%20Services%20content%20goes%20here.%3C%2Fp%3E&backgroundImage=&width=page&cssClass=" />
          </contentFragments>
        </region>
      </regions>
      <contentFragmentTabs />
    </contentFragmentPage>
