Root Element of the V5 query specification. The Query Framework (i.e. the Bering Common Query Engine) expects a valid querySet per request. A querySet has one or more named queries and one or more named queryResultDefinitions(QRDs). Each QRD is based on a single query and must reference it. Multiple QRDs in the same querySet can reference the same query. A QSAPI Masterdataset is returned for each queryResultDefinition specified in a querySet. The expressionLocale attribute indicates the locale of all query expressions in the request. It is required. a set of queries a set of QRDs hints that apply to all queries in this querySet When enabled, query returns sample (fake) data for this request. When enabled, Query Framework applies all design filters that are specified in the model for the query subjects associated with this request.
