Nadine,

You have identified three items:

1) ensure that the address will result in successful routing/mapping  
if used during an emergency call.

  Since this is not done during the emergency call, it would not be  
covered and is not part of the emergency call process.

2) avoid the necessity for default routing

  Determining that a call from a location does not need to resort to  
default routing also does not seem to be covered as this is not part  
of the emergency call process, or at least does not have to be part  
of the emergency call process.

3) avoid associated delays

  This would be covered as it seems to be a performance issue, which  
we only care about during the emergency call process.  A system  
designed only to avoid delays if validation has been conducted  
penalizes the areas of the world where validation does not occur.  It  
also has the undesired effect of requiring re-validation when parts  
of the system are reinitialized for other reasons.
