[dns-wg] Deprecation of DOMAIN object attributes

[Apologies for duplicate emails]

Dear Colleagues,

At RIPE 62, the RIPE NCC was asked to look at the attributes in DOMAIN 
objects. A suggestion was put forward to deprecate the following attributes:

mnt-lower:
sub-dom:
dom-net:
refer:

These were considered to be of no use after the removal of forward 
domain data and no longer allowing hierarchical, reverse delegation data.

The RIPE NCC is now removing these attributes from the syntax. It will 
no longer be possible to create objects with these attributes. To modify 
objects already containing them, these attributes will need to be removed.

As a follow up the RIPE NCC will "clean" the reverse delegation and ENUM 
DOMAIN object data to remove these attributes. The web forms for both 
updates and queries will also have these attributes removed.
