Readonly. Unique identifier of the client subscription request. This allows for matching the corresponding subscription and unsubscription requests. Note that, for clients based on a very old version of a client library or text protocol, subscription requests may involve multiple Tables (i.e.: Subscriptions), hence multiple objects of this type can be supplied in a single array by IMetadataProvider through NotifyNewTables and NotifyTablesClose. In this case, the value returned is the same for all these objects and the single Tables (i.e.: Subscriptions) can be identified by their relative position in the array.
