That is essentially how our pages are rendered. Check http://www.wedsimple.com and you can see how our doc type etc is configured. It is the same as what you have outlined above.
If you could email me directly at support at wedsimple.com I can set you up with a test account. So that you can see the page in action.
I've also noticed that your editor code is not XHTML compliant (Transitional or Strict) is this something you have plans to comply with? Or am I perhaps running the wrong version?
Many thanks!
