SYNC_GID Structure
Represents an identifier for an item that is unique throughout the synchronization community.
The GUID component must be unique. This can be accomplished by using CoCreateGuid to generate a new GUID.
Item IDs are not required to be in this format. However, for systems that do not have an intrinsic unique ID for items, we recommend that you use this format.
In situations in which the items that are being synchronized have a hierarchy, it can be useful to place a monotonically increasing number, such as a clock time, in the ID prefix. For more information, see Flexible IDs.
