Ok, thanks for explaining. I am now clear that this is an implementation
of the draft. If this is the case, why didn't the design on the wiki say
this so it is clear which draft version this is based on ?

Already released. If the domain_realm mapping doesn't indicate a
specific realm for the host in question, a referral is requested.

It should "just work". Okay, well, the client code needs to not
specify a realm, or explicitly specify the "referral realm", to get
our library to actually request a referral, but "whatever you need to
do to request a referral" should work. And, for this round, it only
works in TGS exchanges, not AS exchanges. (There are some issues that
require a bit more work to support that case securely.)
