I needed something similar to this too - I then solved this problem
(without elegance) by defining a variable for the preprocessor on the
commandline. With this your example would look like

<if <string-eq "$(FOO)" "francais">
 <set-var bar="true">
 <set-var bar="false">

This works, because $(FOO) will be replaced in pass 1.
To create the slices, you would call "wml -DFOO='francais' ..." and "wml
-DFOO='something-else' ..." .

As I said, not very elegant but it works.
