Mmm....How this traversal adapter would look like? I mean, to solve my
problem I wrote a view for z3c.form.interfaces.IWidget to get the
description as following:

from zope.publisher.browser import BrowserPage

class Hint(BrowserPage):
    """A view that returns the hint from the field"""

    def __init__(self, context, request):
        self.context = context
        self.request = request

    def __call__(self):
        return self.context.field.description

This way I can simply use widget/@@hint and it works.
Am I abusing here? I am interested on how it would be accomplished
with a traversal adapter.
