Right approach.  Every SGML application wants and have to read the DTD
before processing the document instance (the ordinary .sgml file); sx
(resp. sgml2xml) is a SGML application.

Good.  I've my db2xml script (available from
http://www.suse.de/~ke/docbook-toys/) which hides all the nitty
gritties; warning: lately the script was only tested on SuSE Linux 7.1
and 7.2beta.

At this stage these are warnings only.  Once you've the derived XML file
make sure it starts with the DOCTYPE declaration.  Than it will make use
of the XML entity files coming with Norm's DocBook XML package.  On SuSE
you'll find the entities files here:

    /usr/share/sgml/db41xml/ent/iso-*

Sure, but it isn't actually difficult if a db2xml script is in place;
distributor should take care about this issue.

Good :)

You'll work it out.  IIRC, patches were also posted on the openjade
list to work wround compilation issues.
