Exporting Child in the Tree

The export_child message is used to export the request xml or analysis xml from the tree nodes in the Workplace view. In both of these cases the table / index (root to search are known.
To export an item, the sequence of events is as follows:

1. The client sends a message with one of the following types:

Request type = QM for Query Master or QR for Analysis Breakdown

1. The WORK server performs the following steps:
   1. Queries the CRC cell requesting either the Query Master or the Analysis Breakdown.

1. The client receives the request XML received from the CRC.
