That is how I read it, yes.  Also, the absence of the words
"undefined" or "unspecified".  See also:

  1.4.2 Error Terminology

  Situations in which errors might, should, or must be signaled are
  described in the standard.

Which I take as meaning: If the standard doesn't say an error might,
should or must be signaled in a certain situation, then an error must
not be signaled in that situation.
