If you want to use my lately distributed 
rss-feed for dj2 only you can replace
not parse snip [ date ]with
not parse snip [ date #"-" some byte]as it is contained in the 
rss script on line 23 and 24.
Then every dj2-item will be rendered as an rss-item.
Below you can view two screenshots that show how 
Sage displays the two different versions.
