Data Types Issue 52: Missing demotions

Introduction

From Paul and Grahame's last editorial pass for R1 prior to ANSI approval:

It may be necessary to define some new promotion methods in the data types specification to recognize some of the following demotions that do not currently have a promotion method defined for them:

 LIST<IVL<TS>>  -->  GTS
 HXIT<T>  -->  HIST<T>


Discussion

Don't agree with these demotions, or if they are just misrepresented, then they are there.--GrahameGrieve 20:15, 20 June 2007 (CDT)
