Please find enclosed, for weekend reading, a provisional Final Draft 2 of the Version 5.1 IBIS specification document. This includes fixes for 24 of the 25 requested changes. The change list and disposition is also enclosed. Note that the compression of the Descriptor section was not done, as this appeared to make the lists nearly unreadable. We will review this document in our next meeting. If these changes are acceptable, this document will be posted for IBIS Open Forum review by Aug. 10, in preparation for the Aug. 24 approval vote. Comments and suggestions are welcome. - MM
