    NodeError: use a String for the attr_name, not a &'static str
    
    For now, we'll need to keep around attr_names that come from the C
    code.  We don't know if the pointers we are passed are to
    statically-allocated strings or not, so we'll just use full Strings on
    the heap for NodeError.
