Bob,
"source node" might not be sufficiently specific in the case of 
tunneling, and "added" can be read as their insertion is somehow 
independent and we want it to be coupled with the insertion of an IPv6 
header.

I think what we want to say is that extension headers can only be placed 
in packets by the same node that is placing the base IPv6 header in the 
packet. Hence they can not be added unless a preceeding IPv6 header is 
also added.
