[plt-scheme] Webit issue

Hi all,

While using webit! I'm getting the following:
(require (planet "xml.ss" ("jim" "webit.plt" 1 4)))

(define-element foo)
(define-attribute bar:)

(define test
  (foo bar: "test"))

reference to undefined identifier: bar:

I think define-attribute should just do it! However, scheme keeps complaining...

Any ideas?

Thanks,
