Retrieval mechanism

The retrieval mechanism is dependent on the kind of entry that is executed.

1. Entries that collect data through a MQSeries request
   Each time such an entry is executed in an ITP Model the XML MQSeries Connection constructs a XML message. This message is posted on an MQSeries queue. After processing the request, MQSeries returns an answer containing data in XML format to ITP. The XML MQSeries Connection extracts the XML data, converts it to a set of records according to rules in the DID, and returns this to ITP to be processed further.
2. Entries that collect data in earlier in the model collected XML structures
   Entries as described in the previous item can return data in an XML substructure. The XML MQSeries Connection can retrieve the data from these substructures by means of subentries. The XML MQSeries Connection will treat this XML structure in the same way as the XML File Connection does.
