IIRC, that term was added to the standard after the clang Templates were implemented (I remember someone mentioning a big standards 'template' rewrite a few years back), so thats perhaps why it wasn't named that. You can get the same from an expression (isInstantiationDependent, isValueDependent, and isTypeDependent, the latter two having language equivalence, and the former just a catch-all). Feel free to write up some documentation on this in the internals manual, as long as you properly explain the Template Definition Context/etc means.
