Pazpar2 features a cunning scheme by which you can associate various
kinds of attributes, or settings with search targets. This is done

pairs with groups of targets -- for instance, if you would like to
place all commercial full-text bases in one group for selection

+ Clients of the pazpar2 webservice interface can selectively override

+ overriden, to allow use of pazpar2 in a consortial or multi-library
