Is there some reason you have to quote the entirety of 9 msgs to ask this question?

The client of a pkg with a private type does not have visibility of the full
type declaration in the private part. The only things a client can do with a
private type is declare objects of the type and call subprograms operating on
the type. (If the type is not declared limited, the client can also assign
values and call "=" and "/=".)

"Instantiate" is an Ada technical term with a specific meaning relating to
generics. It is meaningless applied to a record type. The Ada technical term is
"declare an object of a record type", often shortened to "declare a record".
