To a certain degree :) The conclusion is true. Right? So i am looking  
for the missing assumption that makes the argument sound. This being  
not an explicit statement in the topic map, but rather something that  
is in the TMDM or TMCL. Or if such an assumption does not exist, then  
the statement would have to be made explicit in [1] - goes for all  
constraint types.
