(I am not retaining the original message.  Please see it separately as 
it is long and detailed.)

I am confused by at least two aspects of the proposals from the document 
authors.

1) I am confused as to why PE is not listed as a viable term for the 
endpoint.  It seems the natural endpoint of the IETF Network Slice (not 
from the perspective of the service user) just as the PE is the endpoint 
of the operators service in the VPN cases, even though the customer's 
focus is on the CE devices.

2) I am confused by the assertion taht the 4G use case requires that the 
end points be the CE.  In those environments, the CE is not under the 
control of the what 3GPPP calls the Transport Network Slice controller. 
  As such, the CE can not be the endpoint of the IETF Network Slice.

I suspect that there are other places where I am misunderstanding the email.
