RSS Feed Requirements/Reading Custom Namespaces

This is a two part question.
I asked this first question in another post, but nobody got back to me.

1.) What is the tag for publishing?
2.) Is there anyway to get AutoBlog to read custom namespaces?

I'm currently attempting to get Auto Blog to be able to read namespaces for an Events plugin to be able to read.

Any help in getting this to work would be greatly appreciated.
