RFCs

Hi,

Could someone point me to a link (or reply) listing which RFCs are supported by ejabberd?

I am interested to know that to implement feature X on the client side, what protocols/RFCs are
required?

For instance, to implement buddy list retrieval, you need to do X
To send a user to user IM, you need to do Y
To do multiway chat, you need to do Z
To do user to user file transfer, W

And so on.

Thanks.

Serge
