It is an interpretation within the domain of the Smalltalk Text class itself, which is a string with per character attributes. My method answers if there are in fact no attributes on a Text.  It therefore clearly applies to the Text class itself and not to some specific domain outside it.  Can we please put it back in the testing protocol of Text?

BTW, if I were going to put it in System-Support I would categorize it as *System-Support-testing, not just *System-Support.
