Section 9.2 says:
The Mobile Configuration Response is used to acknowledge a previously received Mobile Configuration Request, and includes a Result Code message element that indicates whether an error occurred on the WTP. This message requires no special processing and is only used to acknowledge the Mobile Configuration Request. The Data Transfer Request message MUST contain the message elements described in the next subsection.
It should say:

This message requires no special processing and is only used to acknowledge the Mobile Config Request. The Mobile Config Response message MUST contain the message element described in the next subsection.
Notes:
Section 9.2 describes "Mobile Config Response", not "Mobile Configuration Response" (incorrect spelling) or "Data Transfer Request" (an entirely different message type). "Mobile Config Response" is an acknowledgement of "Mobile Config Request", not "Mobile Configuration Request" (incorrect spelling). The next subsection describes exactly one message element.

Notes:
This statement tries to rephrase what the immediately following Section 8.6 says. The second instance of "Request" in the original text should be "Response".

Notes:
This entire section is in the wrong location or needs to be revised. Section 7.2 is the definition for Configure Request, which is suppose to be a message sent from the WTP to the AC. But here at 7.2.3, this message element clearly states it is an element to be sent from the AC to the WTP. Does this section belong in the Configure Response section instead?
[This section does seem to be in the wrong place. However, moving it will need to wait fo a new (revised) RFC. ISE, July 2017]
