That would be privacy breaking, of course: the legality of the source would 
depend upon the private details.

But of course it is legal if you have a tagged private type. (Once done, of 
course, the fact that the type is tagged is visible.) Completing an untagged 
private type with a tagged type causes various semantic issues, so I'd 
recommend against that anyway.
