I would guess the client proxy class generated by svcutil has a field/property called meetingId of type int - right? Yes, this is non-nullable - but I bet you also have a boolean field/property called meetingIdSpecified - only if this is set to true will the service actually look at it; if you don't set it, then the service will not look at the value, so it's almost as if it where NULL.

Also - you didn't specify the field to be nullable in your XSD, either - you specified it to be optional. To make it nullable, use this syntax here:

See the "nullable" attribute? That's the one used for making a field really nullable - you can now have an entry like this in your XML:
