Programmatically (c#) create xml schema

Suppose, I have the following xml schema,

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Tab1">
<xs:complextype>
<xs:sequence>
<xs:element minoccurs="0" maxoccurs="10" name="Test1" type="xs:string" />
<xs:element minoccurs="0" maxoccurs="10" name="Test2" type="xs:string" />
<xs:element minoccurs="0" maxoccurs="10" name="Test3" type="xs:int" />
</xs:sequence>
</xs:complextype>
</xs:element>
</xs:schema>

then, I have to add some additional values with each element
(Eg: state="kerala" url="mylinkurl")

So the final xml schema output will be as follows:
(see the element tags)

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Tab1">
<xs:complextype>
<xs:sequence>
<xs:element minoccurs="0" maxoccurs="10" name="Test1" type="xs:string" state="kerala" url="mylinkurl" />
<xs:element minoccurs="0" maxoccurs="10" name="Test2" type="xs:string" state="tamilnadu" url="mylinkurl" />
<xs:element minoccurs="0" maxoccurs="10" name="Test3" type="xs:int" />
</xs:sequence>
</xs:complextype>
</xs:element>
</xs:schema>

How can add these name & value programmatically (using c#)? Please provide a sample code.
