unexpected behaviour from rdfa distiller

Hi

I'm trying to parse http://wiki.foaf-project.org/w/Special:F2F with
http://www.w3.org/2007/08/pyRdfa/ and expect to get some foaf:member
links. The page describes a group and its members. In the distiller
output, I don't see any 'member' relations, just description of the
group and the agents.

I attach a snapshot in case I break it :)

Rapper and any23 give the output I was hoping for, eg
http://inspector.sindice.com/inspect?url=http://wiki.foaf-project.org/w/Special:F2F&content=
uses the latter.

thanks for any advice,

Dan
