On second thought, I now realize that's the problem.  They ARE zero 
initialized.  The first token is `namespace'.

 std::string XmlTree::_describeToken(size_t index, const std::string& name, 
AST* node) {
    return "\n"
      +_functionCallString(node)
      +"index:"+itos(index)+" "
      +"token:"+name+" "
      +describeToken(_tokenStream[index])+"\n";
  }
<diagnostic>
XmlTree::visitUnqualifiedName(UnqualifiedName* node)index:0 token:tilde 
kind:namespace,position:38,size:0,extra:none
</diagnostic>

Perhasp they could be set to std::numeric_limits<size_t>::max() if not used?  
Or perhaps I should simply test to see if they are zero?
