The downside is that there are dependencies on the storage for what must 
be serialized on the wire.  If that information is not stored as per the 
generic mapping, then the whole mechanism may not work.  Each artifact 
has different requirements for what must be serialized on the wire.  
BIE's need to know what CC they came from, they also need to know the 
contexts (UUID for a set of contexts) that lead to their existence, 
CC's  do not need to know the BIE's spawned from them, yet do need to 
know there are BIE's and provide a mechanism (Classification tree?) for 
others to locate the BIE for a specific set of contexts.

The set of contexts is also another huge problem.  There may be 8-10 
million.  One BIE may be used for a range of contexts (example - all 
french speaking countries and regions).  Just creating that many 
classifications will crash most registry implementations I know of or 
make them unmanageably slow.

These are just a few of the potential problems.
