Kent, Yiu,

As we are working on a statement of compliance for cdni-logging, we are going through all relevant requirements and I noticed: 

"
LI-14  [HIGH] The CDNI Logging interface shall support extensibility
          to allow proprietary information fields to be carried.  These
          information fields shall be agreed upon ahead of time between
          the corresponding CDNs.

   LI-15  [HIGH] The CDNI Logging interface shall support the exchange
          of extensible log file formats to support proprietary
          information fields.  These information fields shall be agreed
          upon ahead of time between the corresponding CDNs.
"
Do we really need two separate requirements to indicate that the cdni-logging interafce needs to be extensible to support proprietray fields?

If yes, can you expand on the subttle difference between the two?

Thanks

Francois
