dotnet svcutil: generate classes from XSD

Hi
I wonder if it is possible to generate only classes (and not the client) with the dotnet svcutil from a set of XSD files. The same way we used to do with the old xsd command line provided the /c switch.
The reason behind this: in our project we need to extract data types from a set of provided XSD files first and write the code for the webservice client manually later.
