This type of errors would not be covered by SC 4.1.1 but would probably lead to SC 4.1.2 failures. For example, if you accidentally write <divid="nav" rol="navigation"> instead of <div id="nav" role="navigation"> then the role of the div will not be programmatically determinable (SC 4.1.2). But if you write <nav id="nav" rol="navigation"> instead of <nav id="nav" role="navigation"> then the role of the element is still programmatically determinable (at least for UAs and ATs with accessibility support for HTML5's nav element). > > > According to some 4.1.1 hardliners, who have seen it as limited to > those 4 issues and on HTML only, they could call it a 4.1.2. > > > > In my mind, 4.1.1 is about mistakes/unknowingly-invalid-use (other > than custom design –which is clearly 4.1.2) in coding – whereas 4.1.2 > is about designing specifically with user agents, AAPI and AT > interoperability in mind when building custom components whether that > is in HTML, scripting or what-have-you. > If elements are not correctly nested (cf. Alistair's message), that would be covered by SC 4.1.1. But not all validation errors and other markup errors are violations of SC 4.1.1; only the types of errors that are listed there should be considered as violations of this SC. If you the code you produce doesn't match an ARIA design pattern, then, strictly speaking, you can't claim to be using the intended technique. It's the code that needs to conform to WCAG, not the developer's intentions. (That's the approach in the WCAG techniques: if your code does not pass the test procedure in a specific technique, you can't claim that your code uses that technique.)
