Our company ramped into SGML by doing conversions from one proprietary format to
another. Even on relatively small data sets, we frequently used SGML in the middle
because tools like OmniMark made it easy to gather semantic information and apply
context-sensitive formatting on the down-translate. This meant that many of our
clients didn't even know that they used SGML. If you looked at this intermediate
data, you would not be able to classify it as SGML or XML - it is both, leaving
the only difference the tools that you use to manipulate the data.
You sound somewhat bitter about SGML, perhaps due to a large and difficult
project, but there are numerous small, simple SGML implementations around as well.
I'm not suggesting this approach is necessarily the norm, but nor do I don't think
that the delineation between what should be an SGML or XML project is as clear as
you imply - in many cases we plan to call the normalised output from an SGML
parser XML. Why not?
