    If I pass a floating point number in XtSetArg, it doesn't work.

Yes, it will; but you have to jump through hoops to get the
C compiler to refrain from doing the courtesy of coercing
your float to an int.  The best way we've been able to figure
out to do this is with a union containing a float and a long.

    I'd like to be
    able to e.g. pass a string and have it parsed by the converter.

You'll be able to do this with an R4-compliant Xt via a new
additional set of interfaces.
