See 8.2.2 section of the specification.

In the code it is said that it is optional:

  /* version is optional, but we do set a default value of 1.0.0, make sure request isn't for something different */
  if(strcmp(params->version, ""1.0.0"") != 0) {
    msSetError(MS_WCSERR, ""WCS Server does not support VERSION %s."", ""msWCSDispatch()"", params->version);
    msWCSException(map, params->version, ""InvalidParameterValue"", ""version"");
