Oracle: Literal translation of EPSG:9122

Description

EPSG:4326 and others have EPSG:9122 as their UNIT. This literally translates to

degree (supplier to define representation)

when pulled from the EPSG tables. Oracle and some others actually *write* this into WKT output, and when I try to get back to GeoTIFF keys with this UNIT, things no longer match and a GeogAngularUnitsGeoKey is not written into the keys.

I don't know enough about this to determine whether or not the translation really needs to happen in the WKT->GeoTIFF code, or the ImportFromWkt code. Any ideas Frank?

Howard, can you provide an example WKT?
