Generally speaking yes, but let's not get lost in academic debate. I didn't mean literally "anything", and I bet you understood. This feature has existed for what, a year? Two? And the docs still doesn't mention it. Like many other features. In this case, having an example with what you think is a confusing form element, is thousand times better than keeping the status quo of a very incomplete documentation. I get frustrated when ever I'm trying to find something. I always have to dig into the source code.
