    You're right, I forgot about that. For no-wait-mode you don't need
    multipart. But it is critical for wait-mode if we are going to send
    complete application/ipp responses for each part, since the version,
    status, and request-id are positional fields.

    But (unless I read it wrong), the current spec allows the printer
    to send multiple event notification groups in a single response,
    so you can get all your events even without multipart encoding
    (for the no wait mode, anyways)
