def makeSubscriberService(endpoint, local_ivo, validators, handlers, filters):
"""Create a reconnecting VOEvent subscriber service.
Parameters
----------
endpoint : implements `twisted.internet.interfaces.IStreamClientEndpoint`
The endpoint to which the service will connect.
local_ivo : `str` or `None`
IVOA identifier for the subscriber.
validators : `list` of implementers of `~comet.icomet.IValidator`.
Validators which will be applied to incoming events. Events which fail
validation will be rejected.
handlers : `list` of implementers of `~comet.icomet.IHandler`.
Handlers to which events which pass validation will be passed.
filters : `list` of `str`
XPath filters. Will be passed to upstream as a request to filter the
alerts being sent.
Notes
-----
Upstream brokes may not provide support for XPath filtering; in this case,
the filters suppplied will be ignored.
Reconnection is handled according to the default policies of
`twisted.application.internet.ClientService`.
