title: Any WYSIWYG rich text editor that doesn't use HTML (contenteditable or designMode), a la (the new) Google Docs?
body: <p>Besides the new Google Docs, all the other WYSIWYG web-based rich text editors (ckeditor, tinymce, old Google Docs) I've seen are based on contenteditable or designMode. I personally hate using these editors. It doesn't take much formatting or copying/pasting before the whole experience turns into an exercise in frustration. Returns suddenly start getting double-spaced, unintended formatting gets introduced via pasting from other HTML sources, undo's/redo's are completely broken, formatting becomes excruciatingly difficult to control, etc.</p>
  
  <p>I believe this is one of the reasons Google Docs introduced its own much more constrained, non-HTML formatting engine. Is there any open-source library out there that provides something similar? Thanks in advance.</p>
