Penalty for losing Capital..how do I ?

[Headlocked]

Basically, I find the Ai tends to treat all cities equally;The AI loses its capital, it hops to another but it as if its attitude does not change I have lost my capital once, and by golly i made damn sure i got peace after that. Lost in the end though, because of the loss of my main financial centre and troop producer.

In real life, losing one's capital is a near-fatal blow to ones reputation, industry, economy, internal stabilty and military abilty.
This I feel, is not adequately presented to the game AI.

I do not want to make the loss 100% destructive- just that the penalties are severe, and the AI should be more aware of them. I think this will make the AI more receptive to diplomacy if you are nearing their capital and they have limited troops available.

I am not an XML-head, but any help would be appreciated.

Thanks,
