Hi folks

I was reading 6696 and 6924 (it's been awhile)  and I need clarification:

1) It appears that 6924 does not support transportation of DSRK key. 
Only rRK and rMSK.  Is that correct?

2) According to RFC 6696 - section 4.2:

RFC 6696: Section 4.2:

     o  The rRK MUST remain on the peer and the server that derived it
and MUST NOT be transported to any other entity.

So why is 6942 transporting the rRK around?
