Those configuration options are incorrectly specified -- I have fixed
them in the provisional version 1.8. In particular:

1. pubsub#collection is used to specify the collection with which a node
is affiliated, not whether the node is a collection node or leaf node.

2. pubsub#node_type has been deprecated in favor of specifying the
'type' attribute in the node creation request.

The text was in error. The node type is not specified via the
configuration form, so it cannot be changed that way. The only way to do
so would be to destroy the old node and create a new one.
