The name of the package to which an element belongs has no bearing on the names of the elements that package contains (that is, the package name is not part of the fully qualified name of the element). Nor does it affect how the element is referenced by a client application. For example, if you move a service called Personnel:GetDeptNames from a package called Admin to a package called EmployeeData, client applications would still reference the service as Personnel:GetDeptNames.
