Updated values for busy state to "true", "false", "error .
Explained inheritance of atomic property.
Clarified differences amongst popups, tooltips, and descriptions. Relevant properties: haspopup, describedby.

Reforumulated Drag and Drop, now only two roles involved: grab for source and dropeffect for target.
Improvements to state and property descriptions.
Additional explanatory language in introductory sections.

Added atomic. There was a contradiction with the default value (true) and the instruction text: "If no value for atomic is set then the behaviour should be to treat the region as if the value were false".
Added relevant.
Clarified that tabindex is not in the aaa namespace, and negative value used to make elements focusable without putting them in the tab sequence.
Indicate that Mapping States and Properties to Accessibility API'sis only a subset of all the mappings.
