+Add support for the "accept" attribute on file inputs.
+
+If the widget's field - if there is one - has the "accept" attribute set (the
+`NamedImage` field has `image/*` set by default) then this is rendered as an
+`accept` attribute on the file input.
+
+This would restrict the allowed file types before uploading while still being
+checked on the server side.
+
+Fixes: https://github.com/plone/plone.formwidget.namedfile/issues/66
+Depends on: https://github.com/plone/plone.namedfile/pull/158

+Rendering field widgets with constraints on allowed media types
+-----------------------------------------------------------------

+The NamedImage already has a constraint on `image/*` mime types for files and
