Hi Axel, All,

You have mentioned that most current ebook readers can not display MathML.

Well, the problem lies in the epub guidelines for the readers.

The problem is even worse. many readers do not even implement the full HTML5
standard. though that is the standard used in the latest epub stadnard.
The fact is to be considered epub readers the do not have to, it is a problem
of the epub reader definition.

The problem is what should ConTeXt output?
Should it output code that implements according to the full epub standard 
OR JUST 
what is handled by most epub readers!

IMHO : ConTeXt should not output XHMTL for epub, but HMTL5.
Yes, yes, I know XHMTL is part of HMTL5.

Another question for me is if ConTeXt should also output code for
the iBooks epub format, (Basicaly epub, but some extras).
There are thing you can do in/with ConTeXt that would work with iBooks
that do not in „ordinary“ epub books.

Then, there is the Kindle format one might want to consider!

Another, question which needs investigation is if the ConTeXt output for epub,
also, implementing the fallbacks for missing features which is required?

Just some added thoughts.

Basically, you can only expect ConTeXts epub output to be a starting point that
then has to be tweak.

regards
	Keith.
