    Public Shared Sub Main()

        Dim schema As New XmlSchema()

        ' <xs:element name="stringElementWithAnyAttribute">

        Dim anyAttribute As New XmlSchemaAnyAttribute()
        extension.AnyAttribute = anyAttribute
        anyAttribute.Namespace = "##targetNamespace" 

        Dim schemaSet As New XmlSchemaSet()
        AddHandler schemaSet.ValidationEventHandler, AddressOf ValidationCallbackOne

        schemaSet.Add(schema)
        schemaSet.Compile()

        Dim compiledSchema As XmlSchema = Nothing 

        For Each schema1 As XmlSchema In schemaSet.Schemas()
            compiledSchema = schema1
        Next 

        Dim nsmgr As New XmlNamespaceManager(New NameTable())
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema")
        compiledSchema.Write(Console.Out, nsmgr)

    End Sub

        Console.WriteLine(args.Message)
    End Sub
