Hi balders!
Well, I guess you didn't read this:
WYMeditor's main concept is to leave details of the document's visual layout, and to concentrate on its structure and meaning, while trying to give the user as much comfort as possible (at least as WYSIWYG editors).
With WYMeditor, the code can't be contaminated by visual informations like font styles and weights, borders, colors, ...
The end-user defines content meaning, which will determine its aspect by the use of style sheets. The result is easy and quick maintenance of information.
