Instructions for creating auto-generated C# classes for ebMS 3.0 headers
(we should end up with this file: ebms-header-3_0-200704_soap11_soap12.cs).

1) Download these xsd files to a folder.
ebms-header-3_0-200704.xsd:
http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/core/ebms-header-3_0-200704.xsd
soap11.xsd:
http://schemas.xmlsoap.org/soap/envelope/
soap12.xsd:
http://www.w3.org/2003/05/soap-envelope/

2) Open a Visual Studio Command Prompt
Then change to the folder where the downloaded files are located

3) Run this command:
xsd /c /n:ebMS3.Soap ebms-header-3_0-200704.xsd soap11.xsd soap12.xsd

I have taken the example ebMS messages from the ebMS 3.0 core spec here:

http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/core/os/ebms_core-3.0-spec-os.pdf

...and extracted them into xml files.
