Indeed - the confusion is mine and I apologize. 

Did the WG reach a recommendation for Errata #1652? I cannot find it in
my archives.

My opinion as a contributor is that we still better reject the errata
but the comment should prompt on the discrepancy between the different
standards, and show that it is not clear from the ITU-T standards the
value 'indeterminate' should be used in ordering relative to the other
levels and in masking. 

Brian, please submit again your errata - so that we can append the
appropriate comment and resolution. 

Thanks and Regards,

Dan
