XStandard

XStandard Lite seems a good XHTML compliant WYSIWYG editor.  But I’m still looking for something that has rich features and the goodness of Table-less design in all accounts.  Content Management Systems like Typolight have a nice way of abstracting the flow, are a good option but then it needs quite a good visualization (unless you are a designer/programmer or such class) which requires a little bit of training.
