Hi,

The resolution does not match the issue. It seems the resolution for LC1 
and LC4 got interchanged in sending out these email.
This is the resolution for LC4 and not LC1.

Regards, Prasad

Thank you for your comment [1].  The WG decided to drop the Editorial
Note in the next publication.

Please let us know if this resolution is acceptable.  Absent a response
within two weeks, we will presume the resolution is acceptable to you.
