using xsd.exe to generate c# files from ereg association

Question

I am trying to convert the XSD to some C# classes. I've done this with plenty of other files, but I am wondering why this one is not working.

The schema information contains a link in the download section to the XSD file which I've downloaded to my local disk. Then ran the XSD command from the ms dev tools.

This is the dump from the command prompt:

C:\temp\XSD>xsd version-13-draft-ivi-xsd-scheme.xsd /classes  /namespace:MyNamespace
Microsoft (R) Xml Schemas/DataTypes support utility
[Microsoft (R) .NET Framework, Version 4.6.1055.0]
Copyright (C) Microsoft Corporation. All rights reserved.
Schema validation warning: The 'http://www.w3.org/2000/09/xmldsig:Signature' element is not declared. Line 17, position 5.

Warning: Schema could not be validated. Class generation may fail or may produce incorrect results.

Error: Error generating classes for schema 'version-13-draft-ivi-xsd-scheme'.
- The element 'http://www.w3.org/2000/09/xmldsig#:Signature' is missing.

If you would like more help, please type "xsd /?".

It seems like the XSD validator can not download the signature namespace. But I an not sure what exactly is happening. Can someone explain what is going wrong?

Download http://www.w3.org/TR/xmldsig-core/xmldsig-core-schema.xsd to your local directory, and add it as another parameter to your command:

xsd version-13-draft-ivi-xsd-scheme.xsd xmldsig-core-schema.xsd /Classes

The xsd you are wanting to import contains a reference to that file, on line 7:

<xs:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="xmldsig-core-schema.xsd"/>
