Hi Norm,
Could you explain why you want to restrict the accepted media types in this
case (Restlet annotated interfaces)?
Another workaround is to add an annotation value such as @Get("xml") to enforce
XML usage. Otherwise, we plan to add a per-application control of the converter
used/excepted and their relative order in next Restlet version. Right now this
setting is global to the Restlet engine.
Best regards,
Jerome

Objet : RE: Re: ClientResource.wrap Response Variants?
Yes but when using the ClientResource.wrap approach you're abstracted from all
of that (the Request, Response, ClientInfo, etc) and the wrap method creates an
anonymous InvocationHandler/Dynamic Proxy that sets the ClientInfo for you like
so...
// Updates the client preferences
List<org.restlet.representation.Variant> responseVariants =
annotation.getResponseVariants(getMetadataService(),
getConverterService());
if (responseVariants != null) {
request.setClientInfo(new ClientInfo(responseVariants)); }
So even if I had previously set my media type preferences on the Request
(through ClientResource.setClientInfo()) the anonymous InvocationHandler
created by wrap will override them and specify all media types that the
ConverterService is capable of handling.
