Remarks
To obtain a new ISyncKnowledge object, first create an IProviderSyncServices object by passing CLSID_SyncServices and IID_IProviderSyncServices to the CoCreateInstance function. Then, create the knowledge object by using IProviderSyncServices::CreateSyncKnowledge.
Be aware that there is no single representation of knowledge. Equivalent knowledge might be represented in different forms and return different values from knowledge inspection methods, such as GetScopeVector, GetRangeExceptions, GetSingleItemExceptions, GetChangeUnitExceptions.
