I just had an “aha” moment, posted over in another thread (link below). But basically… if DT were to support both anchor tags in x-callback URLs and transclusion, it would create a powerful and standards-based solution for the networked-knowledge workflow. Both already a part of the MMD6 spec, and DT3 already supports anchor tags in MMD links—just not between documents. It could be a big win with a tweak to already-existing functionality.
