I think we should explore how we support compound-CRSs, which is done by proj/gdalwarp by using 2 EPSG: EPSG:28992+5709 (this is equivalent to using EPSG:7415 but there are cases, like copdem where EPSG:4326+3855 is used and there is no one EPSG for this).
The OGC Name Specs now accepts CURIEs, and it is explained there how we could support this:
