GUARD event spec incomplete

The spec for the GUARD event type has a few issues...

1. I'm not really sure what to expect for the 'Name' attribute. The spec says...

Name = The (possibly verbose) nickname of the guard affected.

I've listened for some and it seems to be a fingerprint...

650 GUARD ENTRY $5D0034A368E0ABAF663D21847E1C9B6CFA09752A BAD
650 GUARD ENTRY $071C2D9D0E03D75FF30DCCA850BB29CA4A4BB383 BAD
650 GUARD ENTRY $36B5DBA788246E8369DBAF58577C6BC044A9A374 NEW
650 GUARD ENTRY $071C2D9D0E03D75FF30DCCA850BB29CA4A4BB383 GOOD
650 GUARD ENTRY $5D0034A368E0ABAF663D21847E1C9B6CFA09752A GOOD

Is this either a "$[fingerprint]" or nickname? Something else?

2. There's a TODO comment to explain the states.

3. The 'Type' is simply described as...

Type = "ENTRY"

I'm guessing that this attribute is to allow guards to be used for other things in the future. If so then the spec should say so.
