OK, thanks. But my reference was with regard to XML in general in the first
instance, and Adobe's marketing of their schema in the second. Also, Adobe
did not invent XML, it is part extension and part subset of SGML. But it is an
interesting point you raise.
Recently Adobe hosted an Acrobat 5 product launch here and showed these tags in
action by adding them to an existing PDF, which was pretty cool, and then
opening the same PDF on a PDA, using the new Palm Acrobat Reader -- never once
did they mention that the purpose of this application of XML was intended for
people with visual communication problems.
So, since this aspect has been raised, I am researching how XML is impacting on
the use of design applications, such as what kind of industry take up is there,
how is it being used in the production work flow, particularly prepress, and so
on. And judging by your signature, I would presume that you would have some
important insight into how design has been impacted upon in an area I had not
yet considered. I wonder if it is not too much to ask for you to share some of
that insight, perhaps by offering some reference points or even putting forward
some of your own reflections about how you perceive the use of XML where people
who may not be able to use standard design styles are given new opportunities.
