FWIIW, I would also recommend to look at the javax.ws.rs.ext.Providers
javadoc:
http://jsr311.java.net/nonav/releases/1.1/javax/ws/rs/ext/Providers.html
as when implementing your custom message body reader/writer for
versioned media types,
you can get an instance of Providers injected there (via
@javax.ws.rs.core.Context)
and then you can leverage existing message body readers/writers for the
basic media types.
