==== In this release:

controlling execution order for SERVICE.

-- GeoSPARQL: GML handling.

GH-1299 - The GeoSPARQL has acknowledged a mistake in their 
documentation whereby the wrong namespace was being used for "gml:".
https://github.com/opengeospatial/ogc-geosparql/pull/334

This also leads to problems with interoperation with GML data sources.
Unfortunately the change impacts impacts existing data and any spatial 
indexes would will need to be deleted and rebuilt.

validation execution.
