    I apologize if a) this is too late or b) if this is the wrong list.

    I would like to propose a significant simplification of the notifications spec.

    In the current spec it is possible for the subscriber to say what info they want
    in the notification. The adds many layers of complexity that are I beleive
    unnecessary:-
    The subscription objects are variable in size
    The validation of the subscription request is more complex
    The generated messgaes have a varying structure
    The size of events varies significatnly (for some notifiaction methods based on
    UDP this may be important)
    We have to define the behavior of the system in the case where the requested
    attribute(s) dont exist on the printer
    For human readable messages it is not clear what this means exactly

    Just thing of the 400 extra test cases that Tom is going to dream up :-)

    My proposal is to simplify by defining the attributes (a minimal set) that each
    event always sends. In many cases I expect this to me nothing extra beyond the
    set that are always required (printer name , subscription id, job id, etc.) If
    the client wants more it can query
