If you read through Special Counsel Patrick Fitzgerald's indictment of Scooter Libby, besides the charges, you'll see a comprehensive chain of events and you'll also see this passage (I. b.) right at the top:

b. In connection with his role as a senior government official with responsibilities for national security matters, LIBBY held security clearances entitling him to access to classified information. As a person with such clearances, LIBBY was obligated by applicable laws and regulations, including Title 18, United States Code, Section 793, and Executive Order 12958 (as modified by Executive Order 13292), not to disclose classified information to persons not authorized to receive such information, and otherwise to exercise proper care to safeguard classified information against unauthorized disclosure. On or about January 23, 2001, LIBBY executed a written "Classified Information Nondisclosure Agreement," stating in part that "I understand and accept that by being granted access to classified information, special confidence and trust shall be placed in me by the United States Government," and that "I have been advised that the unauthorized disclosure, unauthorized retention, or negligent handling of classified information by me could cause damage or irreparable injury to the United States or could be used to advantage by a foreign nation."

Why mention this if you're not going to make charges related to leaking classified information? Is this simply to lay the groundwork for furhter proceedings? Lawyers care to weigh in? Anyone? Beuller?
