A point of clarification, the inclusion of HTML in KSS blocks is actually a pattern I actively recommend against. It's something I've chosen not to include in KSS core a number of times for exactly this reason (even when my own co-workers submit the PR: https://github.com/kneath/kss/pull/97)

If you're using KSS, I highly recommend tying it as close to your actual markup generation as possible. For me, that means rendering partials directly from rails with dummy objects. That way if the partial changes, the styleguide changes.
