We have concentrated on XML/HTML. I believe that our approach
should be applicable to other formats, but of course some amount
of work will be needed for each format. In emacs, this should
in the end be possible to do what's necessary as part of the
mode used for that format.

If using the same editor, definitely. But we also found that there
can be some personal preferences, so if you changed your preferences,
the display would change.

What exactly do you mean by 'commented part'? HTML/XML comments
like <!-- this is a comment --> ? I think that could be used for
saving some document-specific settings, but it won't be possible
to use this to actually influence the display behavior.
