I think the confusion is stemming from Bingo's replies to Angel concerning the PM he sent to us and so everyone else is only getting half a conversation with no real context.

It was a list of words which essentially break down ANH for the information we CAN draw from that movie. The SW "dictionary" at it's base elements.

For example we don't really know what starfighters the Rebel were flying in ANH till ESB when that Imperial officer says "ship approaching X-wing class". Even then the X-wing is never mentioned in ANH. The Y-wing is never mention in all the movies so they wouldn't be on any list. Neither would the B-wing or A-wing...

The basic term "X-wing" is missing from the ANH list as info we known but would be on the ESB list.

Essentially it's breaking down the basic elements of SW to what we do know starting from the original movies.

Thus far only ANH has been broken down as it's a work in progress. =D
