Thank you, that's very useful; I'd been making the mistake of starting from the DID Document in my sequence of trying to understand, but I see now the service URL must come first, of course, just like a URL has to exist to get to any HTML web page. At this point, is the above already agreed as how the DID naming will operate? Or is it still in flux, as part of what's still being finalized on the "DID Spec Completion Proposals" page, about how service naming is done, etc.?
