The GATT places no limitation on multiple instances of characteristics or
services.  The recommendation to profile writers when duplicate
characteristics exist within a service is that each characteristic has a
characteristic presentation descriptor that distinguishes each instance of
the characteristic.  The same would apply to multiple instances of a
service.  There are other methods to distinguish multiple instances of
services and characteristics including different UUIDs so there isn't a
single approach.  The approach though is specified by the profile.
