I think that we'd rather first decide if it's worth breaking the
compatibility (even if only in terminology) with XPath 1.0 at this
level.

I am not taking position or standing on one side or another, just
raising a red flag that this is impacting backward compatibility and
that we should explicitely document this choice and decide if XPath 1.0
is broken enough to deserve breaking compatibility...
