Description
The table shows relationships between CQL durations and UCUM durations using the ~ operator. This introduces special meaning to ~ that I don't believe is specified elsewhere. If the intention is that the ~ operator should support these notions of equivalence, then that should probably be specified in discussions and definitions of ~ as well (for example, in Appendix B).
The spec also may want to provide guidance for implementers regarding how to calculate equivalence in these cases. For example, how would I evaluate the expression: 365 days ~ 1 'a'?
