"HTTP Method 	Path Template
DELETE 	/session/{session id}/cookie/{name}

The Delete Cookie command allows you to delete either a single cookie by parameter name, or all the cookies associated with the active document’s address if name is undefined. "

This is rather unclear. If the intent is to have an endpoint [...]/cookie and [...]/cookie/{name} it might be clearer to have two sections in the spec because in other places it's assumed that a non-empty match is required in the URI templates, and in any case [...]/cookie/ and [...]/cookie are not equivalent.
