Suggested Improvements:

It appears that there's redundancy in mapping the same information on DocumentReference when it could instead be captured within Attachment. Is it necessary to impose this restriction? Alternatively, could we rephrase it to specify that if the information isn't available in Attachment, it can be accessed through this standard extension?
