Good to know. I have worked in the design of WYSIWYG editing tools for 9  
years, although generally only as a part of my job, and in some years it  
has been a very minor part of my job.

/me not really happy to hear that.

I think Amaya (for all its quirks) is an existence proof that developing a  
CSS-based WYSIWYG editing tool (for HTML plus MathML plus SVG) is feasible  
- although in the case where javascript is applied the problem becomes  
much more difficult.

Sure.

Would a *recommended* way help? Something like establishing a list of  
desired repesentations, and for each one an element and *recommended*  
associated styling? This would be informative - guidance to people  
producing WYSIWYG tools that would help interoperability - and the more so  
if they were more closely involved in reviewing this document during  
development.

I am assuming that tools have a rendering engine that is halfway capable  
(although often no more) of handling CSS, because I think that is more or  
less a necessity now. But they might not be based on an up-to-date  
rendering engine.

There are already people around who document what is actually supported in  
email clients' HTML / CSS rendering, for the use of people who send pretty  
coloured marketing email or who want to send properly structured content  
rather than plain text. Getting some involvement from this community to  
develop a document that was in synch with HTML 5 and what the rest of the  
web is doing strikes me as something that would actually be useful.

Sure. But adding elements isn't an answer as far as I can tell, since  
people who *do* use CSS (and that's quite a lot of people now) will simply  
style more of them in more wierd and wonderful ways, complicating the  
rendering that everyone has to do.

Hmm. Good WYSIWYG editing is indeed a hard challenge - harder than  
rendering, which is why I appreciate the input of developers of editing  
tools to this working group. However I am not convinced that CSS  
attributes are the problem on their own, nor that adding elements is a  
good solution, given that we have to deal with the whole of the web and  
not just the bits that work easily in a given type of tool.
