What about this: fgfs first loads $FG_ROOT/keyboard.xml into the property tree,
as it always did. Then, if localization is requested, the same part that loads/
loaded the strings file does also load a stripped down keyboard file, e.g.
$FG_ROOT/Translations/keyboard-fr.xml. No bindings here, only references:
<?xml version="1.0"?>
<PropertyList>
<input>
<keyboard-map>
<desc>Tableaux des clefs franc,oiwhatever</desc>
<key n="97">
<name>a</name>
<desc>translation of: what used to be q</desc>
<property>/input/keyboard/key[113]</property>
</key>
<key n="113">
<name>q</name>
<desc>translation of: increase speed-up (formerly known as
'a')</desc>
<property>/input/keyboard/key[97]/</property>
<mod-up>
<property>/input/keyboard/key[97]/mod-up</property>
</mod-up>
<mod-alt>
<property>/input/keyboard/key[1234]</property>
</mod-alt>
</key>
</keyboard-map>
</input>
</PropertyList>
And finally, if such a subtree "/input/keyboard-map" exists, _init_keyboard()
goes through this and replaces all occurrences of <property> by the contents
of this referenced node. When it's done, it dumps /input/keyboard (Erik:
delTree()! :-) and moves /input/keyboard-map to /input/keyboard. Viola!

It doesn't write TeX (or PostScript) yet, but it's a start.
See attachment. Just dump it into $FG_ROOT/Nasal/.
