Re: 4.1.2 correct roles

Note there is a connection to function in the definition of "role":
role: text or number by which software can identify the function of a
component within Web content

From my perspective, if something functions as a "link" and your text says
"listbox," then by 4.1.2 you don't have a programmatically determinable
"role" since the text isn't actually describing the function.
