Implement a WYSIWYG document editor in WPF?

Question

How will you approach to implement a WYSIWYG document editor in WPF?

This editor is going to be very similar to WYSIWYG html editors, but back-end data structures do not have to be html. Currently, I have a working version based on mshtml control implemented in c++ (this is pretty much like MS InfoPath). I'm seeking to take out the mshtml dependency from this tool, so using WPF WebBrowser control is a choice I want to avoid.

Basic features to support:

1. Flow style document
2. Supports a basic set of controls (TextBox, DropDown, ListBox, DatePicker, etc)
3. Supports basic styles
4. Supports tables (resize, merge cells, split cells, etc)

Probably not exactly what you are after, but you might like to investigate the FlowDocument support build into WPF as it supports a lot of what you are asking for:
