Summary:
SysML 1.3 QUDV provides redundant ways of naming a Unit/QuantityKind:
<Unable to render embedded object: File (--[if !supportLists]-->a) <) not found.-
[endif]->by naming the definition of the Unit or QuantityKind (e.g., InstanceSpecification)<Unable to render embedded object: File (--[if !supportLists]-->b) <) not found.-
[endif]->by the property Unit::name and QuantityKind::nameThis redundancy is unnecessary; it invites confusion and could also lead to problems of interchange since different users could use different ways of naming what should be equivalent definitions of the same Unit or QuantityKind

Disposition: Resolved — SysML 1.4
-
Disposition Summary:
The duplication is indeed unnecessary. In fact, the none of the definitions of Units
and QuantityKinds in the ISO-80000-1-QUDV library have slots for the Unit::name or
QuantityKind::name properties. Remove Unit::name and QuantityKind::name.
This duplication also applies to:- QUDV::Prefix
- QUDV::SystemOfUnits
- QUDV::SystemOfQuantities
This resolution builds on the resolution to issue 18269 from SysML 1.4 Ballot 4.
