Are you talking about the implementation of xmldb access made by Maciej? 
If yes then it is generic. But if you are talking about storage managers 
(MetadataConfigurationStorageManager, 
SimpleMetadataConfigurationStorageManager) for fetching the information 
from the metadata configuration file (nmwg:store) then it's not generic. 
It's only for MA services (RRD, SQL or others).
