I think Frank was in a hurry, and meant to use A: instead of include:
(Unless I'm missing something.) Here is the revised zonedata:
zonedata:
outer-space.test:
- SPF: "v=spf1 a:inner%_space.test -all"
"inner space.test":
- A: 1.2.3.4
outer-space.xn--zckzah:
- SPF: "v=spf1 a:inner%%space.xn--zckzah -all"
inner%space.xn--zckzah:
- A: 1.2.3.4
- SPF: "v=spf1 a:inner%-space.xn--zckzah -all"
"inner%20space.xn--zckzah":
- A: 1.2.3.5
