DISCUSS:
----------------------------------------------------------------------

I need a bit of help understanding how to read the Security Considerations text
– threats are identified but how they are mitigated seems implicit.  The text,
“In general the same types of attacks … However, the latter will be more
difficult to detect …”, alludes to a similar threat without a reference and
seems to suggest it will be worse in the deployed environment of this extension.

The next paragraph, “Existing security extensions … [RFC5304] and [RFC5310]
apply …” states that [RFC5304] and [RFC5310] also apply.  What does apply mean
here – should they be used?  Do they mitigate what’s described in the previous
paragraph?
