What if the details in the master location were not available at the time that new details
are entered at a new master Location?

What happens if 2 requests are made that contradict each other and there is delay between
the first being updated (e.g. due to communication line down) and the later request for
change occurs first?

This protocol appears to be too simplistic and has communication protocol errors.

How do take care of these protocol errors?
