       Dim sGroup As System.Xml.Schema.XmlSchemaAttributeGroup
   
   
       Sub Main()
           xValidator.Schemas.Add("", "c:\test.xsd")
           xValidator.ValidationType = System.Xml.ValidationType.Schema
   
           sGroup = xValidator.Schemas.Item("").AttributeGroups(sQualifiedName)
   
           Console.WriteLine("Name: " & sGroup.RedefinedAttributeGroup.Name & vbCrLf)
           Console.WriteLine("LineNumber: " & sGroup.RedefinedAttributeGroup.LineNumber & vbCrLf)
           Console.WriteLine("LinePosition: " & sGroup.RedefinedAttributeGroup.LinePosition & vbCrLf)
