If you open reference.cs in you projects servicereference folder you will see that a proxy classes are generated for every thing exposed through web method. Other than those nothing is exposed. Any class that is a parameter, or return type of a webmethod is in exposed at client side of service.
A class is exposed with all child objects, so in short if you want to expose any class to client side then either it has to appear in any web method or as a child class of any other exposed class
