SiteMapConfig Site Parameter

To include data items as part of a Content Site Sitemap versus a separate one, you need to add a SiteMapConfig Site Parameter to the Content Site:

The structure is:

<SiteMapConfig><ExternalRoots><DocID>710</DocID></ExternalRoots></SiteMapConfig>

You can specify any DocID you want and it will include that and all descendant pages in the site map of the Content Site you add the parameter to.
