We need ways to pass variables to the RSS block to turn
on and off RDF/RSS features: like introduction for
links, the links themselves, etc... i.e:
rss_intro = [false|true]
rss_links = [false|true]
rss_other_feature = on|off
To make things more user-friendly, the keywords "on"
and "off" sound better than the programming oriented
techbable "false" and "true". But it doesn't matter
which is chosen, maybe both can be used....
