    "<item rk:ID='r2-435'>paint</item>" & _
    "<item rk:ID='abc-39'>saw</item>"

' Create the XmlNamespaceManager.
Dim nt As New NameTable()

' Create the XmlParserContext.
Dim context As New XmlParserContext(Nothing, nsmgr, Nothing, XmlSpace.None)

' Create the reader. 
Dim settings As New XmlReaderSettings()

End Using

// Create the XmlNamespaceManager.

// Create the XmlParserContext.
XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);

// Create the reader. 
XmlReaderSettings settings = new XmlReaderSettings();
