I don't think that would be very useful since, as you once said, DSSSL-O
is a ghost from the past. We should probably create some tables showing
what is supported by what backend - and then work to fill the gaps.

No need to do so, Didier. I have already extracted all that information
to dsssl/extensions.dsl. It lists all supported nonstandard FOs and ICs
separately for each backend.
