Error Adding Attributes to Root Node

[jmeckley]

[tt]Please set DataSet.EnforceConstraints == false before trying to edit XmlDataDocument using XML operations[/tt]

I am receiving this error when I attempt to add attributes to the root node in asp.net.

Private Sub ViewReport(ByVal Info As DataSet, ByVal xslFile As String, ByVal fPath As String)
        Dim xml As New XmlDataDocument(Info)
        Dim xsl As New Xsl.XslTransform
        Dim writer As New XmlTextWriter(fPath, System.Text.Encoding.UTF8)

        With xml.DocumentElement
            .SetAttribute("Begin", txtB.Text)
            .SetAttribute("End", txtE.Text)
            .SetAttribute("User", User.Identity.Name)
            .SetAttribute("Date", Date.Now)
        End With
        Try
            xsl.Load(xslFile)
            xsl.Transform(xml, Nothing, writer, Nothing)
            Response.Redirect(fPath, False)
        Catch ex As Exception
            Response.Write(ex.Message)
            Response.Write("<p>")
            Response.Write(ex.ToString)
        Finally
            writer.Close()
        End Try

The error occurs on the line [tt].SetAttribute("Begin", txtB.Text)[/tt].
The xml is created from a dataset consisting of 2 linked tables. I want to add attributes to the root node to display in the footer of my report.
