Re: Valuenow not defined for input type controls?

That is not what typicaly happens for comboboxes in real life GUIs. I
believe the nave is used from the children. Valuenow is used on range
objects.

Sorry, I didn't explain that very well nor did I ask the right question.

When I create a combobox using an element other than an input field, I
need some way to set the value of that combobox.  In Dojo we have been
using the ARIA valuenow property since the element that we assign the role
of combobox may not have an HTML value property.  But, ARIA does not
define a valuenow property for combobox.  There needs to be some way to
set the value on a combobox so I think a valuenow or value property should
be defined for all of the form-type roles.

The current Role specification lists the definition for the abstract input
role as, "Generic type for widgets that can have a value."   However,
there is no property defined for "value" is it implicitly assumed?
