multiple site map providers...

I have multiple site map providers....

How do I define more than one in th web.config? with the add? I used the add, but I can't seem to find it for databinding?

    <siteMap defaultProvider="XmlSiteMapProvider" enabled="true">
      <providers>
        <add name="XmlSiteMapProvider"
            description="SiteMap provider which reads in .sitemap XML files."
            type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
            siteMapFile="main.sitemap"
            securityTrimmingEnabled="true"/>
        <add name="FAQSiteMapProvider"
            description="SiteMap provider which reads in .sitemap XML files."
            type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
            siteMapFile="faq.sitemap"
            securityTrimmingEnabled="true"/>
      </providers>
    </siteMap>

then I call it in the fire, worthlessly...

                <asp:Menu ID="menu3" SkinID="menuskin3" runat="server" DataSourceID="FAQSiteMapProvider"
                    MaximumDynamicDisplayLevels="0" StaticDisplayLevels="2">
                </asp:Menu>
                <asp:SiteMapDataSource ID="FAQSiteMapProvider" runat="server" />


I know I'm messed up.
