ISO/IEC/TR 13066-3 (2012-09)

ISO/IEC TR 13066:2012 provides an overview to the structure and terminology of the IAccessible2 accessibility API.
It provides:
* a description of the overall architecture and terminology of the API;
* further introductory explanations regarding the content and use of the API beyond those found in Annex A of ISO/IEC 13066-1;
* an overview of the main properties, including:
* of user interface elements,
* of how to get and set focus,
* of communication mechanisms in the API;
* a discussion of design considerations for the API (e.g. pointers to external sources of information on accessibility guidance related to using the API);
* information on extending the API (and where this is appropriate);
* an introduction to the programming interface of the API (including pointers to external sources of information).
It provides this information as an introduction to the IAccessible2 API to assist:
* IT system level developers who create custom controls and/or interface to them;
* AT developers involved in programming 'hardware to software' and 'software to software' interactions.
