[lmi] Should xml files be installed to a separate directory?

[Greg Chicares]

Now that we've got all these new xml files, I'm trying to
figure out whether it's really useful to install them (and
our older wxxrc and xslt files) to a separate directory,
like '/usr/share/sgml' or '/usr/share/xml'. IOW, we've got
  configurable_settings::xsl_directory()
for reading these files from a special location, and I'm
thinking of simplifying the code by deleting that. But I
don't want to delete it if it really is a better idea to
use a separate directory when installing under *nix.
(Does anyone really do that for wxxrc files anyway?)

We've been using '/opt/lmi/data' for wxxrc files anyway,
and I'm thinking of just putting all xml files there.
I believe the packages supplied to msw end users are
prepared something like this anyway:
  mkdir /lmi-[date]
  cd    /lmi-[date]
  cp /opt/lmi/bin/* .
  cp /opt/lmi/data/* .
so distinguishing directories isn't important there.
