For years, screen readers and browsers have used error correction and heuristics in the absence of explicit information. Thinking for instance about how certain AT will make a best guess for checkboxes/radio buttons without an explicit label and often announce text that immediately follows the control under the assumption that it's most likely the label text...and how those heuristics can often get things wrong and, most importantly, have inconsistent results (since those heuristics are usually undocumented, secret sauce of specific UAs). So I wouldn't quite hold my breath... P -- Patrick H.
