Right, make that 'non-zero length value':

The "enabled by default" phrase is there because to match phrasing in
the Fonts spec which describes default features. Basically, the user
agent should explicitly disable common ligatures but *not* required
ligatures.  And I don't think the user agent should worry about other
ligature forms (discretionary, historical, yadda, yadda).
