11.2.2.2 Response
The SOS GetResultResponse data type derives from the SWES ExtensibleResponse data type defined in OGC 09-001 and inherits its properties.

12 Spatial Filtering Profile
In this profile of the SOS 2.0, the observations offered by an SOS server are restricted to spatial observations which provide a well-defined parameter for carrying the sampling geometry of the
observation. If an SOS server follows this profile, spatial filters can target the sampling geometries of observations.
12.1 Requirements Class: Spatial Filtering Profile
Requirement 102 When an SOS server encounters an error while performing a GetResult operation, it
shall return an exception message as specified in Clause 15 of [OGC 09-001] with applicable exception code as defined in Listing 9. The meaning of each exception code shall be as defined in
OGC 06-121r3 and OGC 09-001.
