def on_start_element_ns(element_name, attributes, prefix = nil, uri = nil, ns = {})
  # libxml-ruby does not provide a mapping from element attribute
  # names to their qname prefixes. The following code line assumes
  # that if a attribute ns is defined it applies to all attributes.
  # This is necessary to support parsing S3 Object ACL Grantees.
  # qnames are not used by any other AWS attribute. Also, new
  # services are using JSON, limiting the possible blast radius
  # of this patch.
