I was thinking exactly the same thing simply because of some of the bits and pieces both in the keying standards and the wiki for this project.
I was hoping for a definitive answer....sigh...., might have to go back to Anna or WAP again.
By the way, WAP did answer my question on Hospital for location, and gave me the same answer that Anna did....whew!....just took several days to get it. At least I am not on the same time constraints with this image set.
Thanks for your kind assistance,
