Hi,

the canonical format for integer types is the decimal representation.
We do not seem to have a mechanism (other than a description statement)
to declare that the canonical representation is lets say hexadecimal.
For example, EtherType <https://en.wikipedia.org/wiki/EtherType> values
are usually written in hexadecimal notation. If I use a plain uint16
to represent an EtherType, it comes out of a datastore rendered as a
decimal number - and all I have is a description statement... Would
be nice to say something like

  typedef ether-type {
    type uint16 { format "%x"; }
  }

in plain YANG to make the hexadecimal format the canonical format. Who
maintains ideas for the next YANG revision?
