Joel,

You are right, the final :: are not needed and will be removed.

Cheers,
Pablo.

Subject: [spring] SRv6 Network programming minor detail

    In reading section 3.1 on the SID format, I noticed a small inconsitency 
    with a large impact.  My guess is that either I am misreading the text, 
    or there is a typo.
    
    The first part of the section talks about LOC:FUNCT and is clear that 
    this uses all 128 bits of the IPv6 address.  I think I understand that.
    
    Later in the section, in talking about arguments, it says 
    "LOC:FUNCT:ARGS::".  Is the final :: intended?  That seems to require 
    that the entire thing fit in the upper 64 bits of the IPv6 address. 
    Which I believe is not intended.  I would have expected simply 
    "LOC:FUNCT:ARGS".
    
    Thank you,
    Joel
