	This example demonstrates a more complex usage of STIX to represent indicators of phishing activity along with suggested courses of action, previous sightings, and handling guidance. 
	
	It demonstrates the use of:
	
	   * STIX Indicators
	   * Simple STIX TTPs
	   * STIX Courses of Action
	   * Handling (inline)
	   * Confidence
	   * Sightings
	   * CybOX within STIX
	   * The CybOX Email Object (w/ Attachment)
	   * CybOX Patterns (condition="Contains")
	   * Controlled vocabularies
