That's not the reason that "SGML is so great". That has NOTHING to do with
it, that's just an added benefit. Using DocBook SGML allows us to mark the
content of the document, rather than the presentation. It allows for
intelligent searching. THAT is why "SGML is so great".

Conversions are just a feature, not the end goal.

That's right, there's no reason to force people to get a better computer.
That's why we should advocate markup languages, and specifically DocBook
SGML. I can grab my Toshiba T1200, fire up Dr. Dos on it from a 720K
floppy, and write my SGML document on that 8MHz 8088, and it will be plenty
fast enough to run my text editor.

DocBook IS a modern format. It's designed for writing technical
documentation, and it allows both vetran documentation writers and young
green ones to use the same language to describe their document. And it's
NOT hard to learn.

The successor to SGML is XML. DocBook is a DTD for both. As soon as the
tools for XML as more complete, we'll be able to change, and it will take
reading a short paper (15 minutes) to figure out what changes need to be
made for the transition. I'm betting that scripting the change from SGML to
XML will work almost flawlessly.

Huh? We're talking about keeping up with current technology in SGML and
XML, not with falling behind by using "word processors".

So don't use all the bells and whistles, just use the basic features of
DocBook, like the tags for paragraph, author information, abstracts,
applications, command replacment, etc. Writing a document using markup
takes little or no more time than writing without. If you want a What You
See Is What You Mean editor, try LyX, and read the HOWTO-HOWTO. Mark just
about swears by LyX, I haven't tried it myself, since it only took me a
couple of minutes to get the emacs RPM installed, and only a couple of hours
to learn it well enough to use it for basic tasks.

Wait, didn't you just say we should STOP catering to the people who only
have a 486?

I don't care whether or not they're impressed with what SGML can do, all
they have to do is add in a few tags that say "this" is an application, and
"that" is the authors name, and "these" form a paragraph, section, or
chapter. It's pretty basic, barely any more complex than HTML, and
certainly a lot more powerful.

SGML is not the assembly language of documentation, it's more like the C of
documentation. To follow your example, plain text was the machine language
of documentation, followed by HTML being the assembly language. SGML using
DocBook is a language like C, and XML using DocBook is more like a really
high level language, which I don't have a "programming" example for. I'm
not opposed to accepting documents in some format other than SGML, but as
someone said, we just put those documents in a pile, and they'll probably
not be as well used, or as well updated, because they don't allow the kind
of information mining that's required to find the useful documents from the
useless ones (for a given task, that is).
