When the TYPOBrowsers plugin is enabled, you may attach special accessibility features to CSS classes when they are applied to anchors with the TYPO3 link browser.
The classes should first be defined in the CSS file specified by RTE.default.contentCSS.
The classes should be part of the list specified by property RTE.default.classesAnchor.
The accessibility features attached to the classes are specified by property RTE.classesAnchor.
