with the user agent probably defaulting the label value to the term value
term mandatory: 0. false 1. true (current)
scheme mandatory: 0. false (current) 1. true
label mandatory: 0. false (current) 1. true
Maybe I'm biased because of the kind of product I work on, but I'd think the most import part is the label to show the user, and being able to relate back to a vocabulary is a secondary concern. I wouldn't want to default to showing term, since it may well be a number or a URI.
