Look into Section 6.1 and the IDNA architecture figure, please.
The authors themselves may clarifiy the reading of the section,
better than you James and me.

============================

6.1 Entry and display in applications

(snip)

In protocols and document formats that define how to handle
specification or negotiation of charsets, labels can be encoded in any
charset allowed by the protocol or document format. If a protocol or
document format only allows one charset, the labels MUST be given in
that charset.

In any place where a protocol or document format allows transmission of
the characters in internationalized labels, internationalized labels
SHOULD be transmitted using whatever character encoding and escape
mechanism that the protocol or document format uses at that place
