???which could be cleaned up a bit like:
"???This well-known advisory transitive BGP

   neighboring IP network or IXP PARTICIPANT should blackhole a
   specific IP prefix."

Well, the intention *is* that "if the IXP supports black-holing, please do".

In implementations like DECIX', the neighbouring IXP participant does not
have to do anything in particular, except "accept the prefix with the
black-hole nexthop".


Maybe more along the lines of

  This well-known advisory transitive BGP
    community, namely BLACKHOLE, allows an origin AS to specify that a
    neighboring IP network or IXP that has appropriate mechanisms in place
    is requested to blackhole a specific IP prefix.
