No Validation errors using XDocument.Validate

[EDN Admin]

Hi,
I am trying to validate an XML file against a set of XSD files but get no errors even when I intentionally change my XML to have errors, like entering special char when the XSD declares the type to be String, and still it validates correctly.
Need help. Below is my code. I have 4 schemas.

Imports System.Xml.Linq<br/>
Imports System.Xml<br/>
Imports System.Xml.Schema
Imports <xmlns:ns=" http://www.test.gov/trip http://www.test.gov/trip
<br/>
Module XMLTest<br/>
Dim errors As Boolean = False
Private Sub XSDErrors(ByVal o As Object, ByVal e As ValidationEventArgs)<br/>
Console.WriteLine("{0}", e.Message)<br/>
errors = True<br/>
End Sub
Sub main()<br/>
Dim doc As XDocument = _<br/>
<?xml version="1.0" encoding="UTF-8"?><br/>
