I don't think we articulated a definite answer to this question.  The desired behavior might not be far from what's currently documented but one or two clarifying statement may be necessary.  To address the questions raised by Carl, I propose that:

1. The "attribute-charset" attribute be required to be the first operation attribute.  [Same as currently documented]

2.  A request (or response) containing more than one "attribute-character" attribute should be rejected.   [As currently documented]

3.  All responses use the same 'valid' "attribute-charset" received in the corresponding request (i.e., the first operation attribute, if supported)  [Might need to be clarified in the current doc]

4.  The IPP object should always attempt to retrieve the "attribute-charset" attribute from the request (i.e., the first operation attribute) even if it has detected errors with the version, operation, or request numbers, and use it in the response informing the error condition.  [Needs to be clarified in the current doc]

5.  Whenever an IPP object cannot obtain a 'valid' "attribute-charset" attribute from the request (because it gets a request without an "attribute-charset" attribute as the first operation attribute or because it's given an attribute set is doesn't support) the response should be given in the server's default charset.  [Needs to be clarified in the current doc]

6.  Reporting a duplicate "attribute-charset" attribute error does not take any precedence over reporting any other error condition.  The IPP object should not need to parse the entire request first to make sure the "attribute-charset" attribute appears once and only once in the request.  [Needs to be clarified in the current doc]

Did I miss anything?
