With a batch request, how can we get the corresponding symbol (RIC) name on each callback? Would ADS fill the attribute with the symbol name for each callback?
RDM Usage Guide specifies the rules for the AttribInfo / msgKey presence on all message types. ADS follows those rules accordingly.
Since presence of the AttribInfo / msgKey is optional, it would be best for the app to maintain own relationship of Handle -> item name. This relationship may be set on individual item request at the request time and for the batch request at the first refresh.
