Not what I wrote.  Please don't put words in my mouth.

Waiting for the 2nd LSR after LSPR was changed, but NOT waiting for 
the first one. This text is still there:

"M2PA SHALL cease transmitting User Data messages after sending the 
 Link Status Processor Recovered message, until it has received the 
 Link Status Ready message ..."

M2PA says you can base an implementation on Q.703.  If Q.703 has errors 
that affect operability of M2PA implementations they should be
addressed.
