I will assume that's a comprehensive list of error conditions - it's certainly a long list. However, it doesn't say anything about the accessibility tree. Is there a specification for how it is constructed? If there is, I can't find it.

Is it possible that different browsers could generate different accessibility trees from the same DOM if the HTML is well formed, but contains invalid nesting? Or does the accessibility tree not take account of an element's nesting?
