[Simple-support] Suppress serialization of empty lists, empty complex elements

[Atkins, B. <Bri...@ne...>]

I have an complex element that is optional:

Using class:
   ...
   @Element(required=false)
   private Server server;
   ...

Server.java:
   ...
   @Attribute
   private String name;
   @Element
   private String serverIp;
   @Element
   private String username;
   @Element
   private String encryptPass;
   ...

Resulting in, correctly:
   ...
   <server name="server1">
	<serverIp>10.10.10.10</serverIp>
	<username>user</username>
	<encryptPass>d8rhnnsdf8</encryptPass>
   </server>
   ...

However, when the value of the server field in the enclosing object is
null, I still get an empty element:
   <server/>

This is also true of empty, non-inline lists.

Is there a way to suppress empty elements all together, or on an element
by element basis?

Thanks!
