@joanmarie I'm trying to wrap my head around what would have to change in order to support the new no default aria-valuenow attribute on a spinbutton. Can you take a look at this?

I'm not sure this is a valid test, but it looks like there is support for a value to have "no value" already in Chrome for this API: https://source.chromium.org/chromium/chromium/src/+/main:ui/accessibility/platform/ax_platform_node_win.cc;l=4580?q=VT_EMPTY%20f:_win.cc

ATK API returns value as a GValue, which I think is a float, so I'm not sure a default value could be anything other than 0?

I think this property can't be anything other than an double: https://docs.microsoft.com/en-us/windows/win32/api/uiautomationcore/nf-uiautomationcore-irangevalueprovider-get_value

This is a string representation of the value, so can be empty string: https://docs.microsoft.com/en-us/windows/win32/api/oleacc/nf-oleacc-iaccessible-get_accvalue

AXValue can return a empty string if there is no value: https://developer.apple.com/documentation/appkit/nsaccessibilityattributename?language=objc
