Accept: application/json+user
will triggeruser
filterAccept: application/json+v1+user
will trigger bothv1
anduser
filters respectively..type(['v1', 'user'])
will trigger also..type('application/json+v1+user')
will trigger also.filter1.use(filter2)
composition works; similar to express-router.filter1.use({ key: [Function] })
json composition works.
