  • Download tests on mobile connections
  • Checking protection against entity attacks

Testing notes for XML

  • Nested entity definitions can expand exponentially ("billion laughs"). The samples here declare no entities.
  • Namespaces change element identity: <name> in two namespaces is two different elements.
