I apologize for not responding to Eric's message before now.

The Precedence Rules are in their own section in the -02 version
of the draft (which is at temporarily at 
until the I-D submission tool reopens after the IETF meeting.)

There is more text about the "Name Length" rule, and wildcards are
now explicitly mentioned.  Your comments on it would be welcome.

These do that:

    tcl.tk	cname	rpz-passthru.
    *.tcl.tk	cname	rpz-passthru.
    *.tk	cname	walled.example.com.

Please consider the new paragraph in Section 5 of the  -02 draft

Is the addtional text about RD=0/1 in Section 5 of the -02 draft enough?
It doesn't mention forwarders avoid needing to define that class
of DNS servers.  Do forwarders set RD=1?  I assume so, but that seems
like something beyond the scope of an RPZ RFC.

Are the additional words in Section 5 and Section 10 good enough?
