Like the MTSEnvironment object, the TableQueue object exposes no methods or properties outside the scope of the CML application. The other server-side components of the CML application can instantiate the TableQueue object and invoke its methods, but it is visible only to them. For this reason, it is simply an object, not a COM component.
