I dont have  currently working code. I have been recommended to  use
XSD.exe to generate the code instead of typing it in.

The auto generated code should have custom attributes (in my example
it its FormMapper)

public class Address
   {

       public Address()
       {
       }

       [FormMapper("TextBox2")]

       public string StreetAddress { get; set; }
       [FormMapper("TextBox3")]
       public string UnitNumber { get; set; }
       [FormMapper("TextBox4")]
       public string City { get; set; }
       [FormMapper("TextBox5")]
       public string State { get; set; }
       [FormMapper("TextBox6")]
       public string zip { get; set; }

   }

What I am trying to do is.
I have to send XML requests to the server based on the events on my
winform applications. They could add/update/get requests. I will have
70-80 different requests types and hence 70-80 XSDs  (or Classes) to
maintain.
I am planning to use reflection to populate fields on the winforms
using the FormMapper attribute.But that may not be the only reason why
i need custom attributes. I mite also need to get someinfo about the
fields(like readonly, enabled ) etc from the server.

TIA
