Editorial: Use of MAY in draft-ietf-ipsec-ikev2-algorithms

Greetings again. The tables in draft-ietf-ipsec-ikev2-algorithms have 
MUST, SHOULD, MUST-, SHOULD+, SHOULD- (which I have proposed 
removing), and MAY. The MAY designation is silly, since an 
implementation MAY do whatever it pleases for non-mandatory 

The reason I bring this up was the proposal that DES should be 
demoted to SHOULD NOT. That is somewhat harsh given that there are 
places where DES is appropriate (low value transactions in 
implementations that already have DES in them). Listing DES as "MAY" 
gives the wrong impression. The document should be re-cast to list 
all the registered algorithms, but to remove "MAY" from those that do 
not have a stronger designation.
