[Developers] uniqueness of /book/book_edition/credited_to

[Brian Karlak]

Hello All --

One other minor proposal in the flurry of book schema proposals:

The "/book/book_edition/credited_to" property is currently unique.

However, books can have multiple authors, some of which can be  
pseudonyms.  In these cases, it seems that we should allow multiple  
"credited_to" entries.  (The alternative is to use a string like "Jack  
Williamson  and Frederik Pohl", which seems silly.)

Are there any objections to making "credited_to" non-unique?
