Scenario

I have an application using asp.net Master Pages in which I would like to repeat some content at the top and bottom of a page. Currently i use something like this:

Master Page

<html>
  <body>
    <asp:ContentPlaceHolder ID="Foo" runat="server">
    </asp:ContentPlaceHolder>
    <!-- page content -->
    <asp:ContentPlaceHolder ID="Bar" runat="server">
    </asp:ContentPlaceHolder>
  </body>
</html>

Content Page

<asp:Content ID="Top" ContentPlaceHolderID="Foo" runat="server">
  <!-- content -->
</asp:Content>
<asp:Content ID="Bottom" ContentPlaceHolderID="Bar" runat="server">
  <!-- content repeated -->
</asp:Content>

Maintenance

As you know, repeating things in code is usually not good. It creates maintenance problems. The following is what I would like to do but will obviously not work because of the repeated id attribute:

Master Page

<html>
  <body>
    <asp:ContentPlaceHolder ID="Foo" runat="server">
    </asp:ContentPlaceHolder>
    <!-- page content -->
    <asp:ContentPlaceHolder ID="Foo" runat="server">
    </asp:ContentPlaceHolder>
  </body>
</html>

Content Page

<asp:Content ID="Top" ContentPlaceHolderID="Foo" runat="server">
  <!-- content (no repetition) -->
</asp:Content>

Possible?

Is there a way to do this using asp.net webforms? The solution does not necessarily have to resemble the above content, it just needs to work the same way.

Notes

I am using asp.net 3.0 in Visual Studio 2008
