why is proxy code Generated by svctuil so small?

I'm using svcutil to generate proxy code for the following web service endpoint which follows the OGC CSW 2.0.2 (07-006r1) standard for catalog services.

I've downloaded the entire OGC schema files and placed them into my "D:/temp/OGCSchemas/" Directory.

The schema i'm interested in is CSW, however CSW schema includes and imports other schemas and that's why i've downloaded the entire set.

My question is: Why is the proxy code that is generated so small? I can't use that, can it? Was the code generation interrupted by the error/warning i'm getting?

This is my svcutil excecution:

And this is the ogc.csw.proxy.cs proxy file it's generating. (VERY SMALL)

EDIT #1 After reading Yaron Naveh's blog i realized svcutil does not like this http-binding (i guess the way the OGC has it specified). So i replaced the http-binding.wsdl for the soap-binding.wsdl and everything works without errors and a HUGE proxy file is generate as expected.

I had the same problem. My WSDL contained no XSD imports and had 3 bindings: Http, Soap11 and Soap12. Removing the HttpBinding solved the problem.

Aditionally, using the XmlSerialized didn't help.
