Just a quick note on this as I am going through the mails in preparation for 
the WG meeting:

The intended text was to state that the provisioning of the network identifier 
is RECOMMENDED for the pledge, while it is a MUST for the *6LBR* pledge. The 
distinction between 6LBR pledge and pledge is made in the terminology section. 
Here is the change I made in the document to make this clear:

-Provisioning the network identifier is RECOMMENDED.
+Provisioning the network identifier to a pledge is RECOMMENDED.

The excerpt now reads:

"Provisioning the network identifier to a pledge is RECOMMENDED. However, due 
to operational constraints, the network identifier may not be known at the time 
when the provisioning is done. In case this parameter is not provisioned to the 
pledge, the pledge attempts to join one advertised network at a time, which 
significantly prolongs the join process. This parameter MUST be provisioned to 
the 6LBR pledge."

As per 8.4.1, the parameter is mandatory to be included in the CoJP request. 
Pledge obtains its value from the enhanced beacon frames for the network it is 
currently attempting to join, while the 6LBR pledge must have been provisioned 
with it. Let me know if this clarifies.
