AT&T (7018) BGP clue sought

["Justin M. Streiner" <streiner () cluebyfour org>]

I'm trying to track down someone at AT&T that can answer questions about 
their implementation of BGP communities - questions that are not answered 
in their BGP policy document.  Conversations with first and second line 
support people have not been productive.  Any help that someone in a 
network engineering role could provide would be greatly appreciated.
