Issue 8 - Tim Polk DISCUSS

Discuss:
There seems to be an essential disconnect between the conformance 
rquirements and the deployment guidance in this specification

The second paragraph of Section 6 Congestion Control states:

    DCCP has congestion control.  For this reason the syslog over DTLS
    over DCCP option is recommended in preference to the syslog over the
    DTLS over UDP option.

However, in Section 5.1,  Transport

    DTLS can run over multiple transports.  Implementations of this
    specification MUST support DTLS over UDP and SHOULD support DTLS over
    DCCP [RFC5238].

For alignment with Section 6, it would seem that "MUST support DTLS over 
DCCP" would be more appropriate.

Proposed resolution by Sean:
vvv
As noted by Lars (before my time on either the IESG or syslog list):

   If DCCP is available (not usually the case) running DTLS over it is
   trivial, so you could also make this a MUST. DCCP support itself is
   obviously not a MUST.

Maybe what we really ought to be saying is Section 6 (which is just
about congestion control):

   DCCP has congestion control.  For this reason when DCCP is available,
   syslog over DTLS over DCCP is recommended in preference to the syslog
   over the DTLS over UDP option.

and we leave Section 5 alone?

I will defer to Lars on this one.  Since we can't make DCCP support a 
MUST, your suggested text for Section 6 would resolve what remains of my 
issue.
