On the raster side, drivers that derive from GDALPamDataset, that is 
most (in particular JPEG, PNG), etc will automatically benefit from the 
added serialization of the coordinateEpoch in the SRS element of the 
.aux.xml file.

On the vector side, we have no such general infrastructure, so that 
isn't possible currently.
