Hi Rob and Randy,
  Thanks. The reference to RFC6482 clarified the field for me. I leave it to your discretion on whether you want to add a reference or not, but I personally found it extremely helpful. As a followup, why is there no associated error checking for the Max Length field in the IPvX PDUs (to ensure the MUST NOT be less than Prefix Length)?

Regards
Suresh
