Actually, I have very little conversion to do, as the "legacy" is only
about 1 month old.

So this thread has convinced me that moving to XML now looks like a
good idea (but staying with DSSSL for the style-sheets).

Converting the SGML source to XML is not a problem. And I've
downloaded the DocBook 4.0 XML bundle.

But what about tools? Currently I use jade and Norman's  modular DSSSL
style-sheets via the db2html and
db2ps/db2pdf scripts that come with RedHat Linux 6.2. I presume I can
continue to use jade, just changing the -t sgml option to -t xml, but
I presume I will have to upgrade the style-sheets themselves, for 4.0,
but are there different style-sheets for SGML and XML, or is this not
an issue?
