If two organizations have the same namespace identifier, but they are so
far removed from each other (in terms of their industry, chance of
interaction, etc.) then this shouldn't be a problem because such
collisions *should* not occur, and the means taken to alleviate the
possibility may be more costly than if such collisions did occur.
On the other hand, if there are (for example) two different agencies in
the U.S. federal government that happen to use the same namespace
identifier, there is a good chance that such a collision would occur in
data exchanges - therefore, the means taken to alleviate the possibility
may be justified.
