Kristian,

I was instructed to upload draft-ietf-netmod-6991bis-00 without any
changes relative to draft-schoenw-netmod-6991bis-01 and this explains
why there is no address-with-prefix-length. The next version will have
definitions for ip-address-and-prefix, ipv4-address-and-prefix, and
ipv6-address-and-prefix - so not action needed from your side at this
point in time.
