I'm tempted to say "isn't this obvious"?  (The use of RDF for sharing 
application data in a modular, extensible, open-ended fashion as a 
consequence of the general goals of RDF.)

Or am I missing something important (about RSS)?

Or maybe I just happen to have fallen into this way of thinking?  A 
work-in-progress example of something I am developing can be found in "An 
XML format for mail and other messages" at 
<http://public.research.mimesweeper.com/Messaging/draft-klyne-message-rfc822-xml-01c.txt>. 
This isn't immediately obviously an RDF design, but if you peek at appendix 
D...

I'll also note that the design of CC/PP follows a similar pattern, if I am 
understanding your point correctly.

There are also some notes from an internal company presentation I gave 
recently at 
<http://public.research.mimesweeper.com/RDF/RDFMetadataForEndToEndContent.html>

Are we talking about the same general approach here?
