Proposal on applying advisory attribute to "aut-num" object

    Dear colleagues,
    
    at RIPE22 I made the following proposal which I would like to be built
    into the RIPE-DB and other routing registry databases:
    
    The famous "advisory" attribute which seems to be still needed by ANS to
    get their routing done is especially cumbersome because it has to be
    applied to and maintained for every single "route" object.  If the
    "advisory" attribute could be added to the "aut-num" object, entering an
    "advisory" there could cover all routes originated by this AS.  Of
    course the ANS people will have to slightly modify their software.
    
    Example:
    
aut-num:     AS760
descr:       University of Vienna, Austria
descr:       AT
as-in:       from AS679 100 accept AS679
as-in:       from AS1115 100 accept AS1115
as-in:       from AS1776 100 accept AS1776 AS1117
as-in:       from AS1853 100 accept ANY
as-in:       from AS2494 100 accept AS2494
as-out:      to AS1853 announce AS-UDNVIE
as-out:      to AS679 announce ANY
as-out:      to AS1115 announce ANY
as-out:      to AS1776 announce ANY
as-out:      to AS2494 announce ANY
default:     AS1853 100
advisory:    AS690 1:1800 2:1133 3:1239		<<<<<<<<<<<<<<<
