I agree - especially if the references to a specific version are not
actually used.

  C063 [S] A generic reference to the Unicode Standard MUST be made if
  it is desired that characters allocated after a specification is
  published are usable with that specification. A specific reference to
  the Unicode Standard MAY be included to ensure that functionality
  depending on a particular version is available and will not change
  over time.

Is the text ever used without an explicit indication of the character
encoding?In other words, does content rely on the encoding being a
particular default?

Its certainly easier to change the default now rather than later. Also,
its off for the XML companion file to have one default encoding (UTF-8 or
UTF-16) and the WebCGM to have a different one (Latin-1).

We should use the correct term, character encoding. Character set has a
different meaning.

  A character encoding scheme, together with the coded character sets it
  is used with, is called a character encoding, and is identified by a
  unique identifier, such as an IANA charset identifier.
