Package Names and Service Names
The relationship between the package name and the folder name can cause confusion. The name of the package to which a service belongs has no bearing on the names of the services and folders it contains. Nor does it affect how it 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" you will not affect client applications that reference that service; it will still be referenced by the name "Personnel:GetDepNames."
Because the fully qualified name of each service must be unique within the server, you cannot have two identically named services in two different packages on the same server.
