I'm trying to figure-out how to share content between two doc sets, while keeping their source files in separate folders—and I haven't had much success.
I started by creating one ditamap with about a hundred *.dita files in the same directory. Today, I started on a second document, and I want to keep the ditamap and *.dita source files in a separate directory. Both of these directories are subdirectories inside my project directory (beside one another).
I can generate the doc for both doc sets at once—using a ditamap that includes the two other ditamaps; but what I would like to do is generate each doc set separately. When I do that though, I get broken URLs—to topics that are not in the same folder as the doc set's ditamap. What is it that I'm not doing (that I should be doing)?

Thanks,
Chris.
