1) The approver (that's me) agrees with RFC 2278:

3.5.  Usage and Implementation Requirements

   Use of a large number of charsets in a given protocol may hamper
   interoperability. However, the use of a large number of undocumented
   and/or unlabelled charsets hampers interoperability even more.

   A charset should therefore be registered ONLY if it adds significant
   functionality that is valuable to a large community, OR if it
   documents existing practice in a large community. Note that charsets
   registered for the second reason should be explicitly marked as being
   of limited or specialized use and should only be used in Internet
   messages with prior bilateral agreement.

The approver has a hard time seeing that the added value over SCSU and 
UTF-8 is enough to be "significant". Are there applications (not toolkits) 
today that have committed to converting to use of BOCU-1? Is the Unicode 
Consortium considering adding BOCU-1 to its specifications?

2) The approver agrees with the submitter that putting the usability 
information into the registration is probably a Good Thing.
