I guess that might be a matter of definition.
I wouldn't consider the empty string a valid path though I understand 
that this may be what people expect now given that this behavior has 
already been established.

I've worked around the issue I had with the "wix-fix-root-dir-prop" 
topic for now so there is no immediate need to change behavior before 
the 3.1 release.

Thanks  for the feedback.
