Of course, however there is no 22048 id in Gandi (the Registrar), yet it
appears in .ch, and 17870 is still Active (as of this moment in time).  

What I can't figure out is how/when does .ch query the CDS/CDNSKEY data.

I know that I can make the domain validate by manually putting a
keyid+data in Gandi, but the whole purpose of CDS/CDNSKEY is to not have
to do that, no?
