PS 3.3 C.12.1 SOP Common Module in Table C.12-1 defines SOP Instance UID
as follows:

"Uniquely identifies the SOP Instance."

A unique identifier is defined in PS 3.8 Section 3.7:

"Unique identifier (UID): The scheme used to provide global unique
identification for objects. It uses the structure defined by ISO 8824
for OSI Object Identifiers."

Is that sufficient ?

I'll be good enough to prove that my software is following standard.
