Bug ID: 27079
Summary: Clarify simultaneous implementatinon of MSAA + UIA and
MSAA + IA2
Product: HTML WG

How is a server supposed to simultaneously support MSAA + UIA Express and MSAA
+ IAccessible2 where the MSAA part differs?
As one example, the spec currently maps the HTML element ARTICLE to
ROLE_SYSTEM_GROUPING in the UIA column, but ROLE_SYSTEM_DOCUMENT in the IA2
column.
A user agent can only implement one COM object per node. The MSAA / IAccessible
part is shared; it can't change what it returns from get_accRole depending on
whether the client speaks UIA or IA2, because there's no way for it to know.
