These methods are invokable when the event type is START_TAG:
  
  public int     getAttributeCount()
  public String  getAttributeNamespace(int index)
  public String  getAttributeName(int index)
  public String  getAttributePrefix(int index)
  public String  getAttributeType(int index)
  public boolean isAttributeDefault(int index)
  public String  getAttributeValue(int index)
  public String  getAttributeValue(String namespace, String name) 
  By default, xmlns and xmlns:prefix  attributes are reported
If the http://xmlpull.org/v1/doc/features.html#process-namespaces
feature is true, xmlns and xmlns:prefix  attributes are not reported 
unless http://xmlpull.org/v1/doc/features.html#report-namespace-prefixes is also true.
