999999 seems like the front-runner at this stage. I have a couple of concerns:
(1) As I recall, Oracle SRIDs are often not the same as EPSG codes. While 999999 looks better at this stage, an official "not applicable" EPSG code would be even better. (2) Oracle use this for "unknown SRID", which is not quite the same thing as Andrea's case, which might be more a case of "not applicable". The representation of "nil" data reminds me of the five OGC urn:ogc:def: reasons. https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/OgcURNScheme These are fine hairs to split, but we are about to establish a de-facto standard. Kind regards, Ben.
