It's not clear why you need a new XML format for config. It seems rather optimistic to assume that a format almost identical to RSS/Atom entries will retain a text-only content model. That is how RSS2 started out.
Won't be long before you see <description>My <b>awesome</b> new extension!</description> All of the widget platforms will have to ship a feed parser anyway. Use a content model identical to an Atom Entry or RSS2 Item, so we don't get another title/link/description format and accompanying semantic drift. It occurs to me that a feed of widgets might be neat. -- Robert Sayre
