Done at last. The updated document has two new sections:

  2. Deployment Considerations
     - discusses the logging implications of the various Softwires
       transition methods, as well some considerations arising out
       of the architectural role of the NAT.

  3. NAT-Related Events and Parameters
     - is a description at a generally coding-independent level of
       the events to be logged at NATs and their associated parameters.
       In principle the contents are the same as in the IPFIX
       document, but some reconciliation may be required.

These sections are followed by SYSLOG-specific stuff: applicability 
statement, parameter and event encoding (with lots examples of complete 
logs), and an extensive IANA section. Then the usual remaining sections.

Comments are welcome. Fire away.
