Hi Sergey,
Nothing is really cast in stone. I was asked to include examples and, naturally, I followed the approach in Jersey. REST assured, will have time to find the best solution and API for this when the time comes.

The acceptance of text/event-stream will be enabled by an SSE enabler annotation. IMHO this will be more JAX-RS friendly. We would even use Response with EventSource. Open question: how to tell the consumer about a field format, guess SSE allows for custom headers/extensions, may be 'comment' can be used as a container.

That said, perhaps in this case, EventOutput would have a way to set Content-Type of the field. This approach still looks less JAX-RS friendly
