Correct. Reinette suggested to have "no domains" means ALL the domains. Would "*" be more intuitive? Whatever is done here to describe the "wildcard node", would it be worth having the node field parse the same way in the "schemata" files? Is there any merit in having range match expressions, e.g. something like 0-3,8-11=foo;4-7,12-*=bar (The latter is obvious feature creep though, so a real use case for this would be needed to justify it. I don't have one right now...) [...] Cheers ---Dave
