Hi Erik, At the last face-to-face meeting, the working group resolved to nullify the offending action item you mentioned below, so the spec change that would result in the problems you identify below will not be made. We trust that this satisfies your last call comment. Thank you, John Boyer > > All, > > Let's continue with some schema questions.
