Thanks, Robin - very helpful.

The upside of the seamless approach seems to be that it does the right thing WRT the included content's type, etc. (as Ian mentioned). However, making it work in older browsers looks a lot more involved. Turning my library into a shim for seamless would require code both in the including context and included content, AIUI.

If there's interest in specifying an 'include' tag, I'd be willing to do the work (spec and code), but otherwise it sounds like leaving things as-is is the right thing to do.
