    ' Create a new StringBuilder object. 
    Dim builder As New System.Text.StringBuilder()

    ' Create the StringWriter object with the StringBuilder object. 
    Dim writer As New System.IO.StringWriter(builder)

    ' Write the schema into the StringWriter.

    ' Print the string to the console window.
