Diplomacy Features explained

[Hafenguy]

Hi Folks,

as every one here I love civ 4.
Discovered this mod but didnt start playing it until now.
I just scrollen through this forum and discovered the new diplomacy Features.
Especially Interesting sounds this one:
Right of Passage, Trade Agreement, Common Market
• Military Pacts: Non-Aggression Pact, Co-operation Pact

I dont have access to my Laptop at the moment so I cant read the civilopedia.
Is anywhere in the forum explained what These Features will do in detail?

There's a hover tooltip for them in-game. NAP is open borders for military units + attitude bonus (if sustained?). Cooperation allows trading units.
