Is _type parameter name configurable?

Hi,

Is it possible to change (configure) the "_type" parameter [1] name to something else?
I want to use (or allow) a different name such as "fmt" instead.
Or is there any way to customize this?

Thanks!

Thank you so much, Sergey!
My client wants to use a different name which they have used with a legacy solution.
Thanks again for detailed explanation!

Cheers,

Woonsan

We've been following the convention that so called system queries should 
start from '_' for them not to interfere with application queries such 
'type', 'format', etc

Probably the simplest way at the moment is to register custom CXF in 
interceptor which will replace 'fmt' with '_type', for example:

public class UpdateQueryInterceptor extends 
AbstractPhaseInterceptor<Message> {

     public UpdateQueryInterceptor() {
         super(Phase.UNMARSHAL);
     }
     public void handleMessage(Message message) {
        String query = (String)message.get(Message.QUERY_STRING);
        int index = query.indexOf("fmt=");
        if (index != -1) {
            String newQuery;
            if (index > 0) {
               newQuery = query.substring(0, index);
            }
            newQuery += "_type";
            newQuery += query.substring(index + 3);
            message.put(Message.QUERY_STRING, newQuery);
        }

     }
}
etc...
and register it within jaxrs:inInterceptors
