[orca-list] About accessible features of ROLE_UNKNOWN

[leena chourey <leenagour gmail com>]

Hello Orca Developers,

Can anybody tell about What accessibility features atspi ROLE_UNKNOWN has? 
As said in the doc: Accessibility Namespace Reference. :

"ROLE_UNKNOWN

The object contains some Accessible information, but its role is not known."

But I am not able to find those features Or how can we add feature to any GNOME widget.

with regards
