That would require a TeX-y who knows the TeX relationships of the files.
 From what I can see jadetex and pdfjadtex are used by docbook-utils, so 
whatever they need to be built and used.
 From docbook-utils /usr/doc/html/docbook-utils-0.6.14/jw.html:

"The jw shell script allows to convert a DocBook file (or some other 
SGML-based format) to other formats (including HTML, RTF, PS and PDF) 
with an easy-to-understand syntax. It hides most of Jade's or OpenJade 
complexity and adds comfortable features.

Other scripts like docbook2html, docbook2rtf or docbook2ps provide 
different ways of calling jw that might be easier to remember.

For the moment, jw does not handle XML, but only SGML.
This utility assumes that several other components are installed. The 
list includes:

the ISO character entities for SGML
James Clark's DSSSL engine, jade, or an equivalent parser like OpenJade
the DocBook DTD from the OASIS consortium
Norman Walsh's DocBook modular style sheets (or some other set of DSSSL 
style sheets)
Sebastian Rahtz's jadetex set of TeX macros for jade (for backends 
intended to "printing" formats like PDF, RTF or PostScript)
A perl interpreter (for backends that use perl)
SGMLSpm from CPAN (for backends that use sgmls)
Lynx HTML browser (for the txt backend)."

I don't know if that gives anyone TeX-y enough information to say which 
more recent dependencies are necessary, although previous releases of 
htmlxml required fontsrecommended, and none of its dependencies now do, 
so it should be required by one or more of those.

It looks like some tools are last century and others more than a decade 
old, so nothing is likely to happen with those legacy projects.
The source documents could do with being converted from legacy SGML, TeX 
formats to something modern like restructured text, and modern tools 
used to generate output formats if required, although browser extensions 
provide readable output from many modern formats.
