I cannot help thinking that if the group seriously considers being able 
to do business without semantics a positive rather than negative 
feature of today then there is some education necessary. If you are 
Ford, or Shell, it may be that you are able to bully your suppliers 
into a single accepted standard for the meanings of terms; however, 
even there there is a semantics -- it may not be written down, it may 
not be negotiable, and if you are not Ford etc. you may not have a say 
in it (and there get a chance to influence it) but hey you STILL have a 

The difference between a written down semantics and a 
back-of-the-envelope semantics is not that there is no semantic 
attachment to verbs such as "open_this_account"; its simply that the 
meaning is opaque and inherently fragile. (If you write both the 
customer and supplier `agent' then this may not matter very much; but 
if I write the customer agent and you write the supplier agent, then we 
begin to get into trouble fast.)
