[ipv6-wg@ripe.net] Creating a route object in the database for IPv6: not possible yet?

I certainly missed something in the discussion but I cannot register a route object for my new sTLA. Apparently, the proposals described in <URL:http://www.ripe.net/ripencc/about/presentations/apricot0202-extending-rpsl /> were not implemented (the database keeps telling me ***Error: Syntax error in "afi inet6 2001:0910::/32" or "class invalid" if I try a route6 object). Is there a proper way to register route objects for IPv6? How people who built BGP filters from the database do?
