[DDI-SRG] DataKind

[Wendy Thomas]

This came up during our TIC meeting. Ken mentioned it. I don't recall 
seeing this email, but my brain has been turned off for a week so I may 
just not recall it.

There is a reason for Data Source to be in Data Collection. Each Data 
Collection activity may have a different Data Source and there needs to be 
a clear connection between these. Why is it important to you that it be in 
Study Unit?

Also, is it clear that the reason I'm asking about DataKind is that in 2.1 
the DataProduct and the DataSource were a unique set (1..1) and in 3.0 
there can be a n..1 (product to source) relationship
