The File Heirarchy Standard reserves the /usr/share hierarchy for
architecture independant data files.  If the app-defaults files
are considered architecture independant, they should reside in
/usr/share on FHS compliant systems.  However, if they're
considered to be architecture specific, then /usr/lib/<app>/...
is probably the better place.  My understanding is that they are
architecture independent however, so /usr/share seems to be the
right place for them.

On FHS compliant systems, the xdm config files seem to fit best
in the /etc/X11/xdm part of the hierarchy, which I believe is
where most Linux distros install them currently.

The xkb data files also seem to be architecture independent data
which fit into the FHS's /usr/share category.

There may be additional files/dirs in the tree which make sense
to move to /usr/share for FHS compliance also.  If I notice others,
I'll pass them along here for comment too.
