* This class is in the <code>shared</code> package because we use it in both

* the client code and on the server. On the client, we verify that the name is
|
|
* valid before sending an RPC request so the user doesn't have to wait for a
|
|
* network round trip to get feedback. On the server, we verify that the name is
|
|
* correct to ensure that the input is correct regardless of where the RPC
|
|
* originates.

* <p>
|
|
* When creating a class that is used on both the client and the server, be sure
|
|
* that all code is translatable and does not use native JavaScript. Code that
|
|
* is not translatable (such as code that interacts with a database or the file
|
|
* system) cannot be compiled into client side JavaScript. Code that uses native
|
|
* JavaScript (such as Widgets) cannot be run on the server.
