Hi Mike. Long time no see! 

The group has been focused on a core, least common denominator, POI encoding. I think accuracy would be defined in an optional extension. I think the CRS used implies a level of accuracy, But since we adopted GML geometry, I bet with some research we could get explicit accuracy information right into the Point, LineString and SimplePolygon elements, but the work hasn't been done yet. 

The OGC: Making location count...
