The way many providers use the IRR info is to take the adjacent ASN and do a reverse index lookup on the origin field. That is, for AS1234, what are all the route and route6 objects with that as an origin. If you need something more complicated, you can use an aut-num object to say that an as-set, route-set or combinations of these ought to be folded in when creating the filters.
fwiw, i build filters by running peval() over their as-set randy
