What is nodeContainsText(localName: String) good for?

What is nodeContainsText(localName: String) in
scala.xml.parsing.FactoryAdapter good for? The local name just doesn't
suffice to decide whether an element might contain text or not, you'd
need at least the namspace URI in addition to that.

Oh, and since the only implementation of FactoryAdaper is
NonBindingFactoryAdapter, was there a plan to have a
BindingFactoryAdapter too, and what should have been the differences
between the two?
