well.. this is already an old point of discussion with the guys in
Bruker... the same
"Ab-initio structure solution from powder data as part of the
Rietveld refinement process"
is also announced in their workshop in August in Glasgow.

What is the boundary between "structure solution" and "Rietveld
refinement"? It is true that there is a lot of confusion and the 
name "Rietveld" is used everywhere... but is it still a "Rietveld
refinement" something that starts without actually knowing the structure?
maybe it is an ab initio structure refinement... or...
now we need more hints...

why not... but also the opposite would not be bad... ;o)
