resolves #1407 by changing example in aria-brailleroledescription - #1409

+1 looks good

Although... consider using <section> instead of <div role="region"> and not using aria-labelledby?

I wanted to show this used in combination with an explicit role. The aria-roledescription section already has both the implicit and explicit role examples.

i.e. 42 landmarks might be a bit much, but 42 h1's is probably ok? :)

Removed the number and changed the roles to article, based on discussion in the call today.

Thanks @cookiecrook !
Should Example 31 use HTML <article> (instead of <section>) for consistency?
