However, for current markup proposal, web is major target medium, 
which means that if markup will not be suitable for rendering in web browsers
then proposal is pointless.

This is partly true. However we can't do much here.
Complexity of task of tranforming LaTeX to XML+CSS depends only on LaTeX, XML and CSS, 
if it is complex it is complex regardless current proposal, if it is easy then it is easy regardless our efforts.
Current proposal is intended to mirror existing niche in XML+CSS framework and provide approprietely
documented markup suitable for usage on web. Choosing completely different approach would require
browsers to implement something that goes far beyound existing capabilities of their rendering engines 
and current scope of web standards, and would turn proposal into yet another long and sad story
of mythical mathematical markup born to save the earth, but being blocked by evil browser developers
failed to fullfil  its mission.

Backward compatibility will be provided exactly as defined in the position paper 
submitted by Opera and Mozilla that represents the fundamental principles 
upon which the WHAT working group intends to operate:

	BACKWARDS COMPATIBILITY, CLEAR MIGRATION PATH
	Web application technologies should be based on technologies authors are familiar with, 
	including HTML, CSS, DOM, and JavaScript.
	Basic Web application features should be implementable using behaviors, scripting, and style sheets in IE6 today 
	so that authors have a clear migration path. Any solution that cannot be used with the current high-market-share 
	user agent without the need for binary plug-ins is highly unlikely to be successful.

Very well, our points of view are very close.

Think about existing technology for web delivery of scientific content.
This is the area where all the problems come from.

This is absolutely realistic, and seems to be the only way to reduce loss of valuable data
during conversion from LaTeX based authoring format to HTML based web delivery format (still suitable for direct authoring).

Keep in mind that apart of authoring current proposal has to take into account other issues including web delivery.
If authoring is the end of story, then paper and pen are more then sufficient.
