Thomas, So you are thinking that numeric ranges are a special case? I
don't see that as a requirement so much as a question for the user
interface that helps non-programmer developers create an application
profile. The W3C work is definitely based around code, not a friendly
interface, so something is going to be needed for people who don't code.
Whether DCMI can provide that is another question.
But I'm open to hearing from others how specific we should be here.
