If you don't mind creating a rather more difficult-to-maintain DTD, you
can always take an existing DTD and edit it by hand. Cumbersome but
possible.

It does claim that the TC provides this.

Personally, I'd say yes: a decent XML editor would understand RNG/RNC,
W3C Schemas, and DTDs.

But IMNSHO it is just as important that you pick an editor whose
interface you feel comfortable with. I you're going to be using an
editor for a long time (maybe the rest of your life), you need to pick
something usable. Read Michael Sperberg-McQueen's very excellent advice
