There's only been one example given, and there isn't any deployment of the specified semantics AFAIK -- reinforcing the notion that doing so is bad practice. And, as a reminder (sorry for sounding like a broken record), the whole point of SH is that we're not mapping every conceivable field value into the data model; just the conventions that are useful (in other words, paving the cowpaths).
