+            <remarks>
+            The parameter's public property values and public field values will be matched against the expected object's
+            public property values and public field values. The first mismatch will be reported and no further matching is done.
+            The matching is recursive for any property or field that has properties or fields of it's own.
+            Collections are supported through IEnumerable, which means the constraint will check if the actual and expected
+            collection contain the same values in the same order, where the values contained by the collection can have properties
+            and fields of their own that will be checked as well because of the recursive nature of this constraint.

+            </summary>
+            <remarks>
+            It is not possible to directly communicate to a real proxy via transparent proxy.
+            Transparent proxy impersonates a user type and only methods of that user type are callable.
+            The only methods that are guaranteed to exist on any transparent proxy are methods defined
+            in Object: namely ToString(), GetHashCode(), and Equals()).
+            
+            These three methods are the only way to tell the real proxy to do something.
+            Equals() is the most suitable of all, since it accepts an arbitrary object parameter.
+            The RemotingProxy code is built so that if it is compared to an IRemotingProxyOperation,
+            transparentProxy.Equals(operation) will call operation.Process(realProxy).
+            This way we can retrieve a real proxy from transparent proxy and perform
+            arbitrary operation on it.

+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them.  Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail kenton@google.com to reserve extension
+//   numbers.  Simply tell me how many you need and I'll send you back a
+//   set of numbers to use -- there's no need to explain how you intend to
