Alternatives MUST NOT include information about the type of object (Editorial & Development)
When using standard controls for links, buttons, images etc. information about its type is assigned elsewhere and should not be repeated in the alternative. This information is generally provided by default for platform objects, controls, or elements and will be announced by speech output software. For example never use the text 'Add button' as an alternative, only 'Add'. Adding additional roles means the role is announced twice to users of speech output software. An exception to this may be when a role or state cannot be added in such as way. For example, in the case of an HTML page tabs that gracefully degrade it may be useful to add the word "Selected" to the link.
Speech output software renders content in the order in which it appears in the document object model (DOM). Place content in the DOM in the correct order either through source code or inserting nodes in the DOM
