Does that mean encrypted or only integrity-protected?

Strange phrasing. Suggestion:

   The design of the CAPWAP protocol MUST protect against any compromises
   of the WLAN system by external entities.

Since this is a basic requirement of all IETF standards, why is it listed?

> 5.2.  Desirable Objectives

Why aren't the items in this section listed as SHOULD instead of MUST?

I found this requirements:

5.3.2.  Technical Specifications

   Classification: General

   Description:

   The CAPWAP protocol must not require AC and WTP vendors to share
   technical specifications to establish compatibility.  The protocol
   specifications alone must be sufficient for compatibility.

   Protocol Requirement:

   WTP vendors SHOULD NOT have to share technical specifications for
   hardware and software to AC vendors in order for interoperability to
   be achieved.

To be a bit bizarre.  Description of what "technical specification" means might
be useful, but I think this is so basic a requirement (the protocol spec is what
gets multiple vendors to interoperability) that it just seems strange to include it.

The introduction to section 5 implies that operator requirements are
valued less than non-objectives.  I don't think that is the message the IETF wants to send to the operator community.
