This is entirely under your control. If you want to give your static text elements descriptions, you can. But, normally people don't do that. For static text, assistive apps would normally use their AXValue (which is the text string).


When you say static text, do you mean AXTextField? I was thinking of the actual string, the AXValue. I guess I still don't have the accessibility nomenclature quite straight.


Note - I don't think any ui elements provide AXDescriptions automatically. It always requires some sort of programmer effort; either using IB, accessibilitySetOverrideValue, or just implementing the attribute directly in a custom class.

Your comment makes me think you might not be using AXDescriptions correctly. Usually, elements with AXValues or AXTitles don't need descriptions. A good example where a description would be needed is an icon button. It has no title (or it's the empty string), so you add a description. Another case could be a button where the title is misleading, like a natural logarithm button on a calculator, "ln", should probably be given the description "natural logarithm."


Yes, you're right. Thanks for clarifying that.
