Testing KASP, CDS, and .ch

The owner of domainmail.ch will need to give .ch an updated copy of the DS record that contains 17870.

Once that has been accomplished .ch will start telling the open internet to expect 17870 when talking to domainmail.ch.  When the open internet matches what it expects with what it gets then DNSSEC will be validated.

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?
