Hey Bryan and others interested in AccName. I'm still validating test cases as part of fixing implementation bugs and found another instance where I think the current implementations are correct (according to the algorithm) and our expectations (WG and Bryan's tool) are wrong. The case in question is test case #558: ==== if given <input type="text" value="peanuts" id="test"> <img aria-labelledby="test" src="foo.jpg"/> then the accessible name of the element with id of "test" is "peanuts" ==== The image is labeled by the input. But the only thing exposed by the input is the value attribute. So calculating the name from the input beginning with step 2 (i.e. current node is the input), we get: * 2A doesn't apply: The input is not hidden * 2B doesn't apply: Calculating a name; the input lacks aria-labelledby * 2C doesn't apply: Calculating a name; the input lacks aria-label * 2D doesn't apply imho: I don't see value as an attribute that defines a text alternative. And when I look at the name calculation stuff in HTML AAM, it doesn't say value is such an attribute. See section 5.1.1. * 2E doesn't apply: The input is not embedded within the label *for another widget* (emphasis added). So while the input is referenced by aria-labelledby, I think that's trumped by the fact that what references it is an image rather than a widget. * 2F doesn't apply: Input/textbox doesn't allow name from content. * 2G doesn't apply: Input is not a text node. * 2H doesn't apply: The input is not a descendant of an element whose name is being computed. * 2I doesn't apply: The input lacks a tooltip attribute. * 2J doesn't apply: Because there is no 2J. But I bet you didn't know that without looking at the spec because the algorithm is insanely long and you lost count some time ago. :) End of options. Empty string. And that's what the implementations say too. What say y'all? Thanks in advance! --joanie
