[j-nsp] Juniper firewall chain behavior

Ok, if this is actually documented somewhere I'll be damned if I can find 
it. When you do:

interface ge-#/#/# {
    unit 0 {
        family inet {
            filter {
                input-list [ filter1 filter2 filter3 ];

What is the behavior for evaluating a packet across chains? If you have an 
explicit "then accept" or "then discard" in filter1 does it end 
processing, or does it then move to the next filter? I would normally 
expect that it would behave similarly to policy chains, but since there is 
no "next filter" command I'm suspicious that it actually does something 
like fully evaluate filter1, then fully evaluate filter2, rather than 
compile it into one ruleset.

The documentation says absolutely nothing about the behavior, as best as I 
can tell.
