David, I doubt that is what you intended, so maybe you want > to word it a little differently. Actually, it was what I intended when I made that comment, BUT, I had not considered the scenario you describe above ... and so, I now agree with you. Therefore I'll withdraw my [T.31] comment provided that the possibility of multiple "ErrorRecoveryLevel 0.5" levels of support is described in the overview section to be added on error recovery.
