I would like to add operations that can be used to "push" data to the
parser asynchronously:

class Parser
{
public:
  virtual void setLocale (const char *) = 0;
  virtual void setEntityResolver (EntityResolver &resolver) = 0;
  virtual void setDTDHandler (DTDHandler &handler) = 0;
  virtual void setDocumentHandler (DocumentHandler &handler) = 0;
  virtual void setErrorHandler (ErrorHandler &handler) = 0;

  virtual void parse (SAXString systemId) = 0;
  virtual void parse (const InputSource &input) = 0;
  virtual void asynchId(SAXString systemId) = 0; //for error reporting
  virtual void asynchPutBlock(const char* buf, int len) = 0;
private:
  void operator delete (void *);
};
