In the section 3.4(multihoming) of draft 
   "draft-ernst-nemo-terminology-01.txt",
illustrated through the figure 8, the draft said the mobile_network_1 is
 single-homed to the Internet through MR1. 

I am confused here,because I don't know where  AR1 attaches to .
if it attaches to the Internet ,then the mobile_network_1 is multihomed 
bacause MR1 has two egress interfaces on distinct link,if not ,why it be a AR?
