I decided to try the same thing, as I know the procedure for Evo.
I got a bit further than you, actually producing a funny-looking page with some XML on it after changing the content type to XML. Very much the same thing that one runs into when you forget to choose {blank} for the template. I tried choosing "Empty" as a template, and was rewarded with a hanging Ajax "updating" thingie. I thought, OK, I’ll cobble together a template containing only "content". Nope, that hung, too. Geez, you can’t change templates sometimes? Freaky!
Back with Evo, I look in the snippet for clues. I went to Package management to see if I could find some notes. Nope.
Oh well, more Revo learning curve, I guess. Mamma mia.

Sorry, I don’t know. Maybe somebody else knows.
