The law simply states three types of case:
1) Someone with authorised access to classified information (for example the "take" of an operation) learns the identity of an undercover operative (for example the Ambassadors wife). That person then reveals the identity of the undercover operative to someone not authorised to know. As long as the suspect KNEW the person was undercover and was being protected, then revealing the identity IN ANY WAY is a crime.
2) Someone with authorised access to the identities of covert agents (ie instead of deducing it from other information, the identity is spelled out) who reveals that identity. with the same caveat in regards to knowing they were undercover and being protected.
3) Someone who doesnt have authorised access to classified informatiion but learns the identity of a covert agent and then reveals it with the specific intention of outing an undercover agent, for the purposes of damagaing the ability of the government to gather intelligence information and as part of pattern of such activites
Nowhere in the law does it say that the person has to be named, just identified - ie, Wilson's Wife is more than adequate identifying information.
The first case is meant to prevent someone from saying "I did not officially know the identity, I worked it out myself based on information I had seen"
The second is the straightforward crime of being told the iendtity and leaking it, and the third is to prevent a reporter from being arrested for revealing an agent, but to prevent the type of case where a reporter, for instance, goes out of their way to repeatedly expose agents with the express purpose of damaging intelligence gathering abilites.

The only things in question are whether Rove knew she was undercover and her identity being protected, and whether he had authorised access to classified information. He definiately identified her, to someone not authorised to have that info.
Two pieces of a puzzle in order to get an indictment, and neither of those should be too hard to get proof of - Rove works in the Whitehouse, and he had access to classified information - the only question is, was it authorised. The second is also pretty easy to prove - The fact that he knew she worked at the CIA when NOTHING else said she worked at the CIA (ie she was "employed" by a front company) shows that he must have known she was covert.
However proving that is needed for conviction, NOT indictment.
