I suppose I asked the wrong question - it should have been 'what is the BCP
for filtering outbound announcements'.

Apparently the consensus is to do it with route-maps, communities, and
prefix-lists rather than access-lists.

Thank you to William Charnock for privately sending an example showing how
to do this.
