Yeah, I knew this would come up pretty quick.

This is absolutely one way to handle this problem. It's ambiguous no doubt, but I would hope the publicationStatement to capture the details "as they appear on the source of information," or whatever the phrase is. The "publicationStatement" would provide the transcribed view while the above would be for data purposes only.

Agreed, but to some extent our options are limited and there may only be imperfect solutions. I'm open to them all, however.

All good points.
