In general though, ASNs are following: http://www.space.net/~gert/RIPE/ipv6-filters.html
I don't know how common the strict/non-strict case is though, but looking at GRH (http://www.sixxs.net/tools/grh/) it seems that most ASN's are properly filtering, thus using the strict model.
The strict filter is still broken in at least one way.
Then mail Gert Doering about it, if he doesn't know he can't update it ;)
ipv6 prefix-list ipv6-ebgp-strict permit 2001:500::/30 ge 48 le 48

Note that there are /45's, /46's, /47's and /48's right now. The filter allows only /48's. Of note, this will break access to the F-Root name server, we announce it from both a /47 and a /48 (local peers only) in IPv6.
I believe there are other issues with the strict filter, but don't have the time to track them down right now.
If you have them, please pass them on to Gert and possibly also spam ipv6-ops. Greets, Jeroen
