Subprograms can be compiled on their own, without being enclosed in a 
package. See, for example, RM 10.1.1(31). (In that example, the 
subprogram is a child of a package, but that is not essential.)

In my applications, such stand-alone subprograms are often generic, and 
their instantiations occur in a package and use the rich environment 
that the instantiating package provides. But also non-generic 
subprograms can be compiled on their own.
