there is a draft out describing this list and idea, and the main issues with
this are
 a) it is trying to make statements at one node in the tree about nodes further
    down.  There is no inheritance in the DNS. Sooner or later it involves
    tree climbing, which is an undesired feature, see RFC 5507.
 b) it can always only be an incomplete list because it tries to enumerate
    those domains for which there is no common policy to be assumed - which
    is a basic feature of the whole DNS tree. Again, see RFC 5507, section 4.

The problem IMHO is less how to put this information into the DNS (TXT, SRV, NAPTR,
URI, new RR type), but where exactly to put it.
