When would such information be absent yet still relevant? In the only concrete example that you have given, there is no visual output, so there's no caret, so the blink rate is irrelevant. > Consider two scenarios: > > 1.

Sure, this exists (e.g. the caret in RISCOS does not blink) and is supported (the period returned is 0). > 2. The UA cannot provide a blink rate (for whatever reason).

If there is no concrete scenario where this happens, then there's no point discussing it. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
