Re: [netmod] inet:ipv4-address

[Juergen Schoenwaelder <[e-mail]>]

The zone identifiers you find in practice are either numeric
(interface indexes) or symbolic interface names, this is also stated
in the description.

          The zone index is used to disambiguate identical address
          values.  For link-local addresses, the zone index will
          typically be the interface index number or the name of an
          interface.  If the zone index is not present, the default
          zone of the device will be used.

in other words, its 'not usually very long' but there is not concrete
restriction. Note that the interface name leaf in RFC 8343 also has no
restriction.

It is good practice to have maximums on input strings and I have come across xml validation rules that require exceptions for long strings - and the definition long is not usually very long.
