Error while trying to validate a schema   

Hi All,
I am trying to write a generic tool that would do XML validation. i
came up with the following few lines
            Dim oSettings As New XmlReaderSettings
            oSettings.ValidationType = ValidationType.Schema
            oSettings.ValidationFlags =
XmlSchemaValidationFlags.ProcessInlineSchema

      Dim xmlr As XmlReader
            xmlr = XmlReader.Create(reader, oSettings)
            Dim myschema1 As XmlSchema = XmlSchema.Read(xmlr,
AddressOf ValidationCallback)

quite
