Date: 2009-05-14
From: Mark Davis
To: UTC
I had the following action from the UTC:
115 A008 Mark Davis Produce updated proposal for the "operationally X-cased" properties, with more background. L2/08-157 2008-05-20 2008-05-20
Here is the proposal, after revising the names and comments as per discussion in the UTC on May 13.
