You don't have to explain it. Let me try in a different way.

https://tools.ietf.org/html/rfc7950#section-9.1

"For most types, there is a single canonical representation of the
    type's values."

Is it generally ok that the canonical value potentially represents a 
different bit field/value than what the client sent?

If it is (and that's fine by me), I think this should be made more clear 
in the next rev of the YANG specification. I feel the whole 
"canonical/lexical format" concept is underspecified, for instance in the 
case of ipv6-prefix. In the text you suggested before that fixes 
ipv6-prefix. Do we have more types where this needs to be fixed?
