Add examples of right and wrong?

[madsmtm]

I think it'd be nice to have some examples, not as a toolkit developer, but instead as a user.

What I'm looking for in particular would be something like an example of "this kinda of widget should have this role set", "this widget should have these children in this order" or "this widget actually shouldn't even be exposed in the accessibility tree".

Do you think something like that would make sense?
