Yes, if the user-base of n-o [and descendants] could be
maintained/expanded, this could amortise the XML development
costs. I guess up till now ETH student projects have 'built' the n-o aps ?

Why should n-o cater for Adobe which AFAIK is not an ISO standard ?
IMO pdf is like M$-word and top-posters !
My log re. a document which was/is vitally important for me:
pdftotext 7403.pdf 7403fdpTxt == looks OK
-> copy to n-o file for analyses !
-rw-r--r-- 1 root root 187752 Oct 9 21:54 7403.pdf
-rw-r--r-- 1 root root 80366 Oct 9 22:15 7403fdpTxt
n-o size after extensive 'colouring' = 83836
I guess the pdf 'formatting' which this doc. had, eg. 'raised' small
font 'foot note numbers' etc. could be done by n-o's html format
in 85KB size.
So it looks to me as if pdf added 233% for 'formatting', and
n-o would acheive the same with 6%.
But actually the size aspect is irrelevant, compared to the fact
that under n-o I can 'suck the document into my brain' like no
other text presentation system I've ever before experienced.
Why else would I convert from pdf to n-o manipulate-able ?
The extreme ability to 'massage' the text effortlessly adds great
This can't be explained by tecnnical considerations, but involves
psychology, cognition ...etc. which we're not trained in.
You can't make a calculation to prove that JS Bach is 'superior' to
'my boy lollipop'.
The fact that military aircraft [where the best is used] have
heads-up-control: look at the 'target' and have 'natural'
hand controls; is IMO relevant.

Yes. But that's the wrong question: capability is a technical
attribute. What really counts [once the gee-wizz novelty factor
is over] is the utility: i.e. how it makes humans more effective.

Well, I'm waiting. I still remember the predictions for *.net
- was it called ? An old time UseNet contributor calls these fads
"christmas wrappings" for garbage.
It's easy to get carried away with the style and find there's no
