assistive technology a transient object behaves like a non-transient object. As a

result it is likely that this state is not of use to an assistive technology, but it

an object has a role which is not one of the previously mentioned roles. An

example is a table cell which indicates whether or not an email has an attachment,

whether or not an mail is considered spam, and whether or not an email has been read.
