.net schema validation - validation

Question

I am experiencing a problem with validating an xml file against a schema which was generated by svcutil. For the purpose of this question please see below a snippet of code which contains only a simplified XSD schema and the XML document that I am trying to validate:
Imports System.Xml.Schema
Module Main
Dim errors As Boolean = False
Sub Main()
Try
Dim xsdMarkup As XElement = _
<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' xmlns:tns="http://zen/myservices" targetNamespace="http://zen/myservices">
<xs:element name="Car" type="tns:CarType"/>
<xs:complexType name="CarType">
<xs:sequence>
<xs:element name="Make" minOccurs="1" maxOccurs="1"/>
<xs:element name="Model" minOccurs="1" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
Dim schemas As XmlSchemaSet = New XmlSchemaSet()
schemas.Add("http://zen/myservices", xsdMarkup.CreateReader)
Dim doc1 As XDocument = _
<?xml version='1.0'?>
<Car>
<Makee>content1</Makee>
<Model>content1</Model>
</Car>
Console.WriteLine("Validating doc1")
errors = False
doc1.Validate(schemas, AddressOf XSDErrors)
Console.WriteLine("doc1 {0}", IIf(errors = True, "did not validate", "validated"))
Catch ex As Exception
Console.WriteLine(ex.Message)
End Try
Console.WriteLine("Hit <ENTER> to exit...")
Console.ReadKey()
End Sub
Private Sub XSDErrors(ByVal o As Object, ByVal e As ValidationEventArgs)
Console.WriteLine("{0}", e.Message)
errors = True
End Sub
End Module
The validation in this particular case should fail (the 'Make' element has been misspelled). Interestingly enough though it passes.
Any ideas what am I missing in this code?
Your help is appreciated.

All set. I resolved the issue myself. I had accidentally left out the namespaces definition in the XML being validated:
<?xml version='1.0'?>
<Car>
<Makee>content1</Makee>
<Model>content1</Model>
</Car>
should have been:
<?xml version='1.0'?>
<tns:Car xmlns:tns="http://zen/myservices">
<Makee>content1</Makee>
<Model>content1</Model>
</tns:Car>
Validation is failing now as expected.
