Alex, 

That is a good question. We did not think about the special case Form Role which is also a landmark.

https://rawgit.com/w3c/aria/master/aria/aria.html#form <https://rawgit.com/w3c/aria/master/aria/aria.html#form>

I will ask but the value in using IA2_ROLE_LANDMARK is that you know it is a landmark and can then got to the xml-roles attribute to grab the actual landmark type. 

I think that it would be easy to check with the landmark role or the form role.

Brett, would you want to stick with the Form Role or use the IA2_ROLE_LANDMARK for it and then look to the xml-roles for the form role?

We don't have a collections interface for IA2, so if we did want to fetch all landmarks, we have to walk the entire tree in-process, in which case checking the role is about the same as checking xml-roles. Still, it does make sense and I'm happy to accept it given the consensus.
