I don't recommend trying to do that...

To represent that in N3, you'd write

  <http://www.example.org/> rss:description
"<p>...</p>"^^rdfs:XMLLiteral.

I'm not sure how well cwm's RDF/XML writer supports
XML Literals, though.

By the way... I wonder why N3 looks useful for the
task you're working on. For me, when I want to edit
documents, I like a direct-manipulation editor,
ala Amaya or mozilla composer. I use N3 as a
poor-man's user interface for much more structured data,
especially data that includes rules.

Are you thinking of using N3 rules somehow?

Even for somewhat structured stuff, I prefer to use
Amaya and scrape the data out with XSLT.
e.g. the travel schedule on my home page.
