* datetime column selection
* primary key column selection
* output property filter
* options to reduce the bandwidth required for returning record geometries.
- bbox-only=[bool] only return the bounding box in the return geometry
- geom-column=none don't return geometry as part of the return
- simplify=[float] Use ST_SnapToGrid(ST_Simplify(geom, [simplify]),[simplify]) to simplify and reduce precision of output geometry.
- sortby=[+/-][field] support to sorting by a field
* ability to use user defined PostgreSQL functions as per the "custom functions" spec in CQL2.
