Expand description

The type of an accessibility node.

The majority of these roles come from the ARIA specification. Reference the latest draft for proper usage.

Like the AccessKit schema as a whole, this list is largely taken from Chromium. However, unlike Chromium’s alphabetized list, this list is ordered roughly by expected usage frequency (with the notable exception of Role::Unknown). This is more efficient in serialization formats where integers use a variable-length encoding.
