OK, how does that pan out? Querying for String.intern() support 
via a getFeature() call? That'd work, but you need to spell it 
out a bit more, because the naive way of taking advantage of 
interning in a ContentHandler looks disgusting,

    if(name == "elem1")
    else if(name == "elem2")
      // etc
    else if(name.equals("elem2"))
      // etc

A much nicer way of doing it would be,

  if(reader.getFeature(... interning ...))


I could live with this.
