Org is another markup language, org is little higher than say md or rtf
or xml/html which are other markup languages, but it would be much more
work then "minimal layer". It is just half-wysiwyg. It is not
impossible, but is not that minimal either.

What would be a problem there? Probably every text manipulation program
has some kind of plain text storage in it's backend somewhere; be it an
array as in Emacs or some linked structure.

Emacs has Lisp which has lists which lets you build arbitrary structures.

It is trivial to implement hierarchical structures like DOM tree or a
scene graph in Lisp since n-ary trees can be easily created with
lists. Likewise key-value properties like CSS properties are also easily
represented with lists; I guess that is what Emacs text properties
already are.

One could use buffer just as a memory storage and index into it, so
"plain text" is really not a problem. And by the way, it is not so plain
anymore, is utf8, so big part of the work is already done (encoding/decoding).

The only problem I see is Emacs renderer. It just needs a little bit
more flexibility so it can render stuff in layers, on top of each other,
so we could for example render some nice rectangle for a page,  markers where
text on paper starts, ends etc. Also a pixel aligned dragging of objects
with mouse might be useful to have in a wysiwyg application, but is not 
necessary.

I think print view could already be implemented by simply rendering
buffer to svg image and displaying it in another buffer.
