Ken, the navigation tools all use NAV_INPUT_COORDINATES as follows:

point navigation:  NAV_INPUT_COORDINATES="x,y"

rect navigation: NAV_INPUT_COORDINATES="x1,y1;x2,y2"

The query widget has never been changed to allow for rectangle queries, 
mostly because it was originally written to query WMS layers, which only 
allow for point queries.

If you are trying to create a rectangle query tool, I would suggest 
starting from the ZoomIn widget.
