In Section 9.5.4, which describes B!B0Sending Binding Ack.B!B1, the draft saysB!B&

B!B0If the node rejects the Binding Update, a Binding 
 Acknowledgement MUST be sent. If the node accepts
 the Binding Update, the Binding Acknowledgement 
 SHOULD NOT be sent."

The first sentence of above paragraph is not informative and is too general.
What kinds of condition make a Binding Update rejected? 

I know that CN sends a Binding Acknowledgement, 
which indicates error condition, in response to receive 
a Binding Update with H bit unset, when the only followings occurs. 

1. MUST :
  - Insufficiency of the Sequence Number
  - Expired nonce index values

2. MAY :
  - Insufficiency of the resource for caching a binding 

Although the above conditions are mentioned in the preceding sections, 
IMHO, we have to include the detailed condition, where the binding update
is rejected, in the indicated sentence.
