Description:
Context: http://www.w3.org/WAI/PF/aria-implementation/#mapping_events_selection - see the first table for single selection events - the cell for MSAA. Based on a discussion with Alex Surkov (Mozilla), in addition to what is specified for MSAA, there is a SELECTIONREMOVE event when an item becomes unselected. > ... [the table] > misses the case when item may be unselected in single selection select > (no SELECTION event but SELECTIONREMOVE event is expected).

I have created a new test file for this. We need to create a spec and test suite for CAAM 1.1 in https://www.w3.org/WAI/PF/testharness/. I want to sync with the team before doing that. Will upload once there’s a spot for it. I sent it to the list so it won't get lost. http://lists.w3.org/Archives/Public/wai-xtech/2014Jun/0007.html
