Re: Question about using role with main and application

Hi, multiple role values do not get expressed as having the features of
both. The facility to add multiple roles allows for a fallback if a role in
not understood. For example

role="foo main"

as foo is not a known role, main will be used.
It is for cases where new roles are introduced such as below, switch was
added in ARIA 1.1 so some AT may not understand it, therefore checkbox is
included as a fallback.
role="switch checkbox"

If you have content that requires both main and application roles to be
expressed, you can do as below.

<div role="application">


*Please note *that use of role=application is not recommended for large
chunks of content and is often not required. This may be helpful:
