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?
