Dear all,

Thanks for the responses.

I need to raise another question about Joris' code

> (document (assign "draft-mode" "true") (assign "draft-hidden" (macro 
> "body" "")) (assign "draft-shown" (macro "body" (arg "body"))) (assign 
> "draft" (macro "body" (compound (if (value "draft-mode") (value 
> "draft-shown") (value "draft-hidden")) (arg "body")))) "") 
I find that when the draft contains more than a paragraph, then with 
draft-mode being false, it will occupy an empty paragraph. Is it 
possible to reduce this?

Thanks!

Best,

Frank
