What is accessibility? - Learn web development
different operating systems have different accessibility apis available : windows: msaa/iaccessible, uiaexpress, iaccessible2 mac os x: nsaccessibility linux: at-spi android: accessibility framework ios: uiaccessibility where the native semantic information provided by the html elements in your web apps falls down, you can supplement it with features from the wai-aria specification, which add semantic information to the accessibility tree to improve accessibility.

Implementation Details
msaa/iaccessible2 at-spi avoiding memory leaks it is the assistive technology's responsibility to watch for events that indicate when windows or content subtrees are being destroyed, and to release all accessible objects related to that window.

XForms Accessibility
instance node states are mapped to accessibility state constants declared in nsiaccessiblestates interface like it shown below: relevant - state_unavailable readonly - state_readonly required - state_required invalid - state_invalid out of range - state_invalid attributes redefines datatype aria attribute.
