Question 1/X - Reorganization and extension of existing Recommendations Z.311 to Z.323 Considering - that Recommendations Z.311-Z.317 are not changing with respect to TTYs; - that Recommendations Z.321-Z.323 are changing in order to keep pace with current technology; - that basing Recommendations Z.321-Z.323 on Recommendations Z.311Z.317 leads to many problems, exceptions, special cases, etc. when attempting to implement these Recommendations; - that the use of graphics, windowing techniques, screen layouts and associated reference models cannot be fully exploited under the current structure of Recommendations, How should the existing Recommendations Z.311-Z.323 be reorganized and extended to allow maximum utilization of new VDT technologies? Note - Close collaboration is required with Study Group IV, IEC and ISO. ANNEX (to Question 1/X) Identical to the annex to Question 2/X
