In regards to cost of conversion: The osx tool that the makefile
uses to generate postgres.xml has more options available to tweak
the output (not resolve external files into the main file, no
newlines in tags, etc.) After adding a few of those options +
htmltidy, the result is pretty close to the original SGML, barring a
bare newline between <para>'s for example.

The benefit I'm talking about is the ability to do multiple indexes
in one document, which is not possible with DSSSL. In order to do
this, I would have to run the conversion *every time* I wanted to
work on a new release of the manual to bookstores.
