Uhm, I think there are some choices, I hope I'm not just
stating the obvious:

a/ use an XSLT.
 a1/  use that directly in the browser, via a
      <?xml-stylesheet ...?> processing instruction
 a2/  run it once, result is "static" HTML.

b/ use CSS 2 with XML, current browsers can display XML content with
   the help of CSSs
   (however, CSS 2 does not allow one to make element selections etc)

c/ combine them

Are you thinking of a2, using some DTD for the registry documents?

I've set up a dummy text using DocBook (not because I think it
is well suited, but because everything is readily available,
including XSL transformations.) Its structure and content
do not reflect the registry except making stupid references to the
context, for the sake of an example. It shows that (a1) does
not yet work too well; (a1) does work to some extent if you have the XSLT
in local files, at least with Mozilla.

With no fancy style; the "data content" is in test.xml,

http://home.arcor.de/bauhaus/tmp.Ada/test.html  (a2)
http://home.arcor.de/bauhaus/tmp.Ada/test.pdf  (a2', PDF, same procedure) 
http://home.arcor.de/bauhaus/tmp.Ada/test.xml  (original XML file)
http://home.arcor.de/bauhaus/tmp.Ada/test-local.xml
(local XSLT, type="text/xsl", not type="application/xslt+xml")

Done using DocBook XSL stylesheets 1.62.4, a copy of the HTML part
is referenced in the processing instruction in test.xml.
